FSC 642 WEEK 3 HOMEWORK QUESTIONS
1.) The 15-year-old son of a police officer arrives home from school on a Thursday afternoon. He barely talks with his father, with whom he has been having relationship problems, quickly curtailing the conversation as to “how he was doing,” saying that he had not taken a shower after PE, and needed to do so. His dad heard the shower water running, and left to go to get Lottery tickets and pick up some dry cleaning. While out, he happened on the scene of a minor traffic collision, stopping to check on injuries, call his department, and to tell the people involved to move their vehicles from the middle of the street to the curb. Upon his return home, some 90 minutes after leaving, he heard the shower still on. He knocked on the bathroom door, telling his son he was wasting water, and to “get out of there NOW!” Two minutes later, the water was still on, and the dad pounded on the door, ordering his son to unlock it, however there was no response.
The father then forced the door open, finding his son hanging from a towel that was draped over the top pipe of the shower head, and was wrapped around the boy’s neck. The father took down the towel, and removed his son from the shower. Rapid assessment revealed the son to be non-breathing and pulseless. The dad called 911, and initiated CPR. Paramedics and multiple police units responded to the house. There was a brief effort to apply Advanced Cardiovascular Life Support, but the patient was pronounced dead when he failed to respond to treatment for Asystole.
The dad is horribly distraught, insists there is no way his son would commit suicide, and makes the homicide lieutenant present at the scene promise that the person responsible for his son’s murder will be brought to justice.
a) Describe your approach to the medicolegal investigation of this young man’s death (including assessment of the scene, the autopsy, laboratory studies, and any other approaches to forensic death investigation you would employ).
b) What possible causes of death may be found at autopsy?
c) What are the possibilities as to “Manner of Death,” given the circumstances?
d) Based on your education and experience, which Manner of Death do you believe is most probable (appreciating that a definitive decision will be made only after a complete investigation).
2.) A 31-year-old female, married, mother of 3, has been depressed since the birth of her last child, some 3 months previously. On multiple occasions her husband has encouraged her to seek mental health counseling and/or pharmacotherapy for her depression, as well as spiritual counseling, however she has been resistant to doing any of these things. One afternoon, when her husband is away at a business conference, she calls her mother and asks that she take her grandchildren for the day, as their mom needs “a break.” Her mother picks up the children, taking them to her home. The female then ingests the remaining contents in her valium prescription bottle, and begins drinking alcohol. After a few hours, she is still awake and disgusted at her inability to kill herself. She gets into her vehicle, and drives out into the forest that surrounds the community in which she lives.
A truck driver, going home down a small mountain road at approximately 2230 hours, comes upon her vehicle, which has struck a tree. Sitting in his truck and shining his spotlight on the scene, he notes that the female is half-in and half-out of the vehicle, not moving. The truck driver proceeds home, and goes to bed.
A Sheriff’s Deputy, on routine patrol, comes upon the scene at approximately 0530 the next morning. Assessing the patient, he finds her to be non-responsive, non-breathing, pulseless, cold to the touch, and somewhat stiff. Going to work at 0630 the next morning, the truck driver again comes upon the crash scene, however there are now multiple official vehicles present, including the Sheriff’s Department, California Highway Patrol, and County Coroner. The truck driver rolls down his window, and says to the CHP officer “I see you found her.” The CHP officer inquires as to what, exactly, the truck driver means, to which he replies “That’s exactly the way she was when I came by here 8-hours ago.” At this point the CHP officer invites the truck driver to carefully park his truck in an area of road that would not obstruct other traffic, and offers to provide further transportation for the truck driver.
The body is removed to the County Morgue. The Forensic Pathologist completes his initial inspection of the clothed body, following which an external inspection of the unclothed body is conducted, revealing no findings of note. To accomplish his internal autopsy examination, the Forensic Pathologist punctures the skin in the Left Acromioclavicular region to begin the classic Y-incision, upon which he thinks he hears a very faint moan.
a) What are possible explanations for the observation of the Forensic Pathologist?
b) What factors did or could cause this?
c) What actions should the Forensic Pathologist take to address this situation?
3.) Firefighters respond to a report of a house completely engulfed in flames. It takes them some time to successfully suppress the flames. When going through the house to conduct his investigation, the fire inspector discovers a body. Upon external examination in the morgue, it is thought that the remains are those of a male, because of the body size and apparent musculature, although the body is badly charred, and the genitalia are not in evidence. Further external examination reveals obvious skin splitting in multiple sites, instability of the right lower extremity, and open fractures of the skull. Further inspection reveals a collection of blood between the fractured skull and the dura matter, although its appearance is not that classically seen with an epidural Hematoma.
a) What are the possible causes that would account for these pathological findings?
b) How would you approach the medicolegal investigation of this death?
4.) The body of a 41-year-old male is found caught on the rocks of a slow-flowing river. The body is lying on its right side. The decedent is fully clothed, including shoes. There is obvious evidence of external trauma to the body, consisting of facial lacerations. No evidence of blood is found on the rocks. The portion of the face and head in the water do not demonstrate any evidence of bleeding, however a minimal amount of blood is found in the right external ear canal. Upon examination in the morgue, obvious facial fractures are found on x-ray and grossly. A faint fern-like discoloration is also noted over the superior aspects of the anterior chest.
a) What possibilities exist that would account for this patients death?
b) What further findings do you believe might be found at autopsy?
5.) The Medical Examiner’s Office is called by the police to a studio apartment. The occupant of the apartment is a retired lady in her late 70s. When her family could not reach her for several days, they called law enforcement, asking officers to “check on the welfare” of their mother. Upon their arrival, officers found the drapes open, and looking in could see the body of the resident lying on the floor. Upon making entry, the officers found the heat on, and the decedent fully dressed in a blouse, pants, two pair of socks, a sweater, and coat. This they found very suspicious, since the atmospheric temperatures had been in the hundreds, with high humidity, for several days. Examination of the body at the scene revealed no external evidence of trauma. The body was transported to the Morgue for autopsy.
a) What possible scenarios may account for this presentation?
b) What factors might be operative that would cause the scenarios you cite in your response to Question a?
c) What findings from your medicolegal death investigation would support or diminish the likelihood of the above scenarios having occurred?

FSC 642 WEEK 1 HOMEWORK QUESTIONS
1. A 61-year-old gentleman was well known to his neighbors as a friendly man who liked to drink too much. Over the course of 4-6 weeks, the neighbors noticed a change in the man’s personality. He was less friendly, seemed not to remember their names, when he did talk he complained of headaches (of which he had not complained before), and they even talked among themselves as to the unsteady gait and dragging foot they saw when he would leave his apartment. Speculation ranged from drinking yet more, to his excessive alcohol consumption just catching up with him, to a simple function of premature aging.
When the neighbors didn’t see the man for several days, they called the police. Unable to get any response, officers made entry, finding the man in bed, lying on his side, with his face hanging down toward the floor. He was dead. An open wound was noted just above the eyebrow, approximately 2 inches long, with undermining of its superior edge; tissue bridges were seen, as were areas of abrasion above the wound. Apparent black eyes were also noted bilaterally. Blood was noted on his shirt.
a. Given this history and physical description, what injuries or other conditions do you anticipate might be demonstrable at autopsy? Why?
b. Of those possible pathologic findings, which do you believe is the most likely cause of this patient’s death? Why?
2. The forensic pathologist loves to teach, and knows you took courses in Forensic Pathology as part of your Masters in Forensic Science degree. He turns to you, and says “Before I open the head and body, based upon the history we just heard, what is the most likely cause of this poor boy’s death. What is your best assessment of what happened to him, anatomically and physiologically?”
3. The body of a 19-year-old male is found on the roadway, alongside a vehicle that hit a tree. Three of the four doors of the vehicle have popped open. 2 other bodies are also found at the scene. On examination at the Morgue, the decedent above referenced is found to have minor abrasions of his chin and right cheek, and his jaw appears slightly distorted. However, upon palpation of the mandible, it is found to be grossly unstable, with subsequent X-Ray demonstrating 19 distinct fractures of the jaw between the Right and Left Mandibular Rami. At autopsy, his trachea is found to be filled with vomitus. No other injuries are demonstrable, although there is some fluid residue found in the stomach, smelling of alcohol.
a) Given these findings, what are the possible causes of death? Which do you believe to be the most likely cause of death?
b) Is it obvious from the injury pattern where the decedent was sitting in the vehicle? If not obvious, where do you believe it likely the decedent was sitting, and why? How would you go about investigating his location to confirm or refute your impression as to his location in the vehicle?
4. Two guys, ages 27 and 17, met 2 girls, aged 16, at a lakeside resort, asking if the girls would like to take a ride in their jeep. Welcoming the opportunity the girls jumped in, not knowing or not caring that the fellas had been drinking all afternoon. Driving around curving mountain roads at a high rate of speed, the jeep went off a cliff, coming to rest some 100 feet below. The 2 males were dead at the scene, the 2 females unconscious but alive. En route to the hospital by ground ambulance, one of the females suffered cardiorespiratory arrest approximately 20 minutes before arriving in the Emergency Department. A resuscitative effort of 1 hour, including CPR and Advanced Cardiovascular Life Support in the ambulance, was to no avail.
At autopsy, both males were found to have distended urinary bladders (a potential indication of their state of intoxication—alcohol is a diuretic, thus the full bladder; alcohol is also an anesthetic, thus the reason the bladder was not emptied via urination—voluntary or otherwise!).
The first body is that of a 17-year-old male, with no obvious external trauma. Examination of the body is essentially negative. Examination of the skull and brain reveals intracranial hemorrhage.
The second body is that of a 27-year-old-male with no obvious external trauma. Examination of the body reveals 1) atrioventricular bisection of the heart, without significant blood loss, and 2) traumatic rupture of the spleen, again without significant blood loss. Examination of the skull and intracranial contents reveals a hinge fracture of the skull base, extending from one ear to the other, and minimal evidence of intracranial bleeding.
The third body is that of a 16-year-old female. She is noted to have ecchymosis of the Right eye, deep scalp laceration extending from the hair line to just above the Right eyebrow, complete tear through the liver, with approximately 3600 ml of blood suctioned from the abdominal cavity (someone her size probably had a total blood volume of approximately 4000 ml). Her bladder was empty.
a) Please write, in appropriate format, cause of death statements for each of these decedents, and explain your reasoning.
b) Based on the findings reported, can you state where the decedents were likely seated in the jeep? How would you further investigate these deaths to make definite that determination? What other findings of significance would you search for?
c) The bladder of the female was not distended with urine. Does that mean she did not drink a significant amount the day of the Motor Vehicle Collision? Why or why not?
5. I will show you a diagram of this death scene in chat this week:
You are called to investigate the death of a 23-year-old female. She was found in her bedroom by her boyfriend upon his return from work, the victim of agunshot wound to the head. The boyfriend states the decedent has been depressed over the past several months over their relationship. Upon questioning, he insists he did not touch her nor disturb anything in the room, because he could see that his girlfriend was obviously dead.
Examination of the room reveals a bed positioned against the wall, oriented in a North-South direction.A .38 caliber handgun is found in about the mid-position of the bed—vertically and horizontally. Blood and brain matter are noted on the center of the bed, and some blood is also noted on the North wall to the right side of the bed.
The body of a well-developed and nourished female appearing the stated age of 23 is found on the floor to the right side of the bed. She is wearing a robe, which is neatly closed in front. Her Right arm is at her side, and her Left arm is extended above her head. Her left leg is found flat on the floor, bent at the knee like one side of an “M,” and that leg goes behind a post of the bed (upslope of the “M,” bend in the knee, lower leg behind the bed post and extending beyond the lower end of the bed). Post mortem lividity is present, but is not fixed. Rigor mortis is not present. There is a gunshot wound of the Left Temple and another GSW of the Right Temple, each covered with blood, and thus difficult to fully inspect.
FSC 630 WEEK 2 HOMEWORK ASSIGNMENT
1. Discuss postmortem lividity? Define, explain it’s characteristic and the forensic significance?
2. Give an account on the cooling of the body after death with the medico-legal significance? Does the body always cool after death?
3. Discuss rigor mortis? Define, explain the mechanism of its formation and the forensic significance?
4. Discuss putrefaction? Explain the mechanism of its formation, factors affecting its rate and the forensic significance? What is autolysis and what relationship, if any to putrefaction?
5. Discuss the postmortem changes that may take place other than putrefaction? Explain the forensic significance of each?

FIN 454 WEEK 4 HOMEWORK ASSIGNMENT
Problem #1: A firm with a normalized pretax income of $40 million, 25% tax rate, and a Total Debt/Total Capital ratio of 30%, decides to undertake a capital expansion financed by new debt. The new level of debt will raise the Total Debt/Total Capital ratio to 40% (5-percentage points above its industry average). As a result, the firm’s credit rating is downgraded by a full level (say for example, from A to B) despite being secured by specific assets. This credit downgrade raises the firm’s Weighted Average Cost of Capital (aka Required Rate of Return) from 10% to 11.5%
(a) What is the value of the firm prior to the downgraded credit rating?
(b) Assuming the firm’s capital expansion program will lead to a 20% in normalized pretax income what is the firm’s value in the aftermath of the credit downgrade?
Problem #2: How would your answer to Problem #1 change if the debt was unsecured? Specifically, what might the credit rating be under an unsecured format and how would this affect the value of the firm? Explain or provide your reasoning.
