Crime Scene Investigation: Evidence Division

Commanding Officer Captain May’s Directive:

Ladies and Gentlemen, this is a crime scene….and it’s one of the strangest we’ve seen in awhile. We need your input in figuring out just what happened here. Look over the evidence, and tell me what you can deduce. We really need your help on this. The men back at the lab are stumped.

Name: James Smith

Age: 17

Found: Juab High School, Nov. 28, 2012 at 11:25 a.m. Victim was unconscious and face-down.

Condition: Stabilized, comatose. Has wounds along outer, lower arms from a blunt blade. Traces of arsenic found in the victim’s blood stream.


Information and facts that support a claim.



  • Relevancy – How well the evidence goes to support the claim.

  • Sufficiency – How much evidence there is.

  • Reliability – How trustworthy the evidence’s source is.


Direct Evidence

  • Evidence is directly involved with the crime.

    Examples: weapons, traceable elements, DNA

Circumstantial Evidence

  • Evidence that is present at the scene of the crime, but was not part of the crime.

    Examples: Victim’s clothing and personal affects, environmental objects such as leaves and trash.

The following note was found in the Victim’s pocket. It was written on a torn piece of notebook paper in a purple pen.


She found out.



The last texts sent from the Victim’s cellphone went to a disconnected number. The messages are as follows:

At 8:15 A.M.

Hey..I really need to talk 2 you.

At 10:39 A.M.

R you ignorring me?

At 11:15 A.M.

I’m going to just end it. After everything with Kelsey, Its all is getting to be too much. So..don’t be surprised if you never hear from me again.


An empty water bottle. There are trace chemical elements on the bottle’s lip. Two sets of prints were found on the bottle. They belonged to the victim and his girlfriend, Kelsey Hunter.


A large pair of blunt scissors were found beside the victim. They had no clear prints. It appears these scissors were the cause of the cuts along the victim’s outer arms.


Victim’s black and white school bag.


Yellow notebook,

Black file folder,

Novel entitled “Who Will Tell My Brother?”

Large Literature book.

Beside, a black jacket believed to belong to the victim.


Assorted candy and empty wrappers.


The following found tucked in victim’s Literature book: It was written on a piece of plain paper in black ink.


I don’t know what’s going on with you and my sister, but it’s really starting to make me upset. It seems like you text her more than me! I want you to stop texting her. Stop seeing her!!
