AUTOPSY--There are two tutorials to visit that will help with an understanding of how an autopsy is conducted.

HBO--Dr. Michael Baden performs a visual autopsy.
Ed Friedlander, M.D. (pathologist)--gives a detailed account of what is done during an autopsy.

CSI--Crime Scene Investigation

On the CSI website, you can navigate an interactive crime lab, look at cases that were solved on the program, and observe the forensics used to solve it. The handbook section contains information about tools, evidence and procedures. In addition, you can sign up as an agent in order to access online training, police codes, and the CSI leader board. Specific instructions will be given in class.

PERFORMANCE ASSESSMENT--Crime Scene Investigation

POLICE REPORT

I was called to 1524 Hummingbird Lane at 10:30 p.m. The neighbors, Ron (65 years old) and Shirley (60) Ross, met me as I pulled up. They stated that they had arrived home at 10:15 to see a man running from the home of their neighbor. They called the police.

The front door was slightly ajar. Upon entering the house, I noticed that the TV was still on but nothing seemed out of the ordinary. In the kitchen area there was a broken glass next to the sink with what appeared to be blood droplets. The bedroom was neatly arranged except for an overturned jewelry box. The contents were scattered on the carpeted floor. A search of the rest of the house, revealed the body of a female lying in a prone position submerged in a bathtub of water. The body had no visible signs of life, was warm but not stiff. I called immediately for the paramedics and then interviewed the witnesses.

RON ROSS:
“My wife and I arrived home at approximately 10:15 and saw a man run from my neighbor’s house. We don’t know her very well. She only moved in a month ago. I think her name is Beth or something like that, but I don’t know her last name at all. The guy was in such a hurry that he didn't’t even shut the front door. That worried us and my wife ran into the house and called the police.”

SHIRLEY ROSS:
“I think her name is actually Bethany. Everything is usually pretty quiet at her house during the day, but I have heard cars coming and going at night. I think she has a boy friend that pays her a visit.”

AUTOPSY REPORT:
The woman was identified as Bethany Andrews by her sister. She is 26 years old, 5’5” and weighs 140 lbs. Around her neck were fingerlike marks. There was a slight contusion on the frontal area of her head. No cerebral hemorrhage was found upon internal investigation. The lungs contained a small amount of water. There was an enlarged heart with signs of ventricular atrophy. All other organs were found to be healthy and normal. Toxicology results: Large quantity of cocaine in the blood.

ARREST WARRANT:
A search warrant was issued for the boyfriend’s apartment and car. Upon examining these, the police discovered jewelry that had belonged to the deceased. Lab tests revealed that the blood in the kitchen and the fingerprints on the jewelry box did indeed belong to the boyfriend, Joe Cool. He was arrested on charges of first degree murder several days later at the home of his mother.

SCORING GUIDE

You are to write the opening statements for both the prosecuting attorney and defense attorney for Joe Cool. For the prosecutor, describe the story that you believe took place on Hummingbird Lane. Include the evidence you intend to present and how it implicates the defendant. In addition, provide the means, motive and opportunity that the defendant had in order to commit such a crime. For the defense, state your side of the story and the important points that will be brought up to give reasonable doubt as to the guilt of your client. End your paper by stating the verdict and interviewing at least 2 members of the jury.

THUMBPRINT

In the heel of my thumb are whorls, whirls, wheels
in a uniqe design:
mine alone.
What a treasure to own!

My own flesh, my own feelings.
Not other, however grand or base,
can ever contain the same.

My signature,
thumbing the pages of my time.
My universe key,
my singularity.
Impress, implant,
I am myself,
of all my atorn parts I am the sum.

And out of my blood and my brain
I make my own interior weather,
my own sun and rain.

Imprint my mark upon the world,
whatever I shall become.
