Date ____________Period ______



Read the introduction and look the crime scene map INTRODUCTIONThis activity is based on real crime that occurred at Apple Computer Company in the early 90’s

It"s the morning of July 5 in the northern California city of Cupertino. You are working the burglary watch, day shift. As commander of the electronic theft division you have a team of experts, skilled in the collection of all types of evidence relating to theft of computers and electronic stuff. At 9:50 a.m. you get a call that someone has attempted to steal an advanced chip from the Plum Computer Company. You and your team respond immediately to the call. When you arrive, you find that the plant is sealed off and all the uniformed employees in the plant have been confined to a single room, the lounge. Within the hour, the missing chip is found in an envelope in a pile of mail. The envelope was addressed to Gordon Lidy, the security chief of a rival computer firm. A CD was also found in the envelope.

Steve Randak, the president, arrived at 8:50 this a.m. to find the tone-operated security door to his private lab open and the prototype of his new computer chip missing. He immediately pushed the panic button that alerts security to close the gates. The guard at the gate reported that no person had left the plant since 8:00 a.m. today.

Data Chart Suspect



Was the suspect in or near the lab between 7:00AM and 8:50AM? (Use your map of the crime scene and clues to help you)

Fingerprints, white crystals, CD, or the code to lock, blue fibers

Can the suspect be connected with any of the evidence?


Guilty /Innocent

Explain your answer

Steve Randak :The President of the Plum Computer Company Time they arrived at work ___________

Time when they were near or in the lab


Coffee Cart Doug Time they arrived at work ___________

Time when they were near or in the lab


Ginny Fletcher: The Lab Assistant at Plum Computer Company Time they arrived at work _______

Jim Hacker : The Security Guard at Plum Computer Company Time they arrived at work __________

Research: In order to arrest a suspect you must have three things: motive, opportunity, and evidence.

A suspect can not be guilty unless you can prove they had a motive or a reason to commit the crime.

The suspect must have had the opportunity to commit the crime. This means that they were in the place where the crime was committed during the time crime was committed.Evidence is something a criminal leaves behind like fingerprints and fibers. You must be able to connect all of the evidence to the suspect.
