Crime Investigation Lesson Plan Erica O’Rourke | University of South Florida | Sickles High School

Lesson Plan Overview • Students will be focusing on a criminal investigation that will lead them to understanding the different components of blood, the different diseases that are associated with blood and working in collaborative groups using their prior knowledge of the microscope. • Students will be able to compare and contrast different blood slides from our suspects and our evidence in order to find our criminal.

Assessments • White boards individually used during do now. • Class discussion. • Oral questioning throughout lab (documented). • Thumbs up/Thumbs down. • Short group presentation. • Written summary submitted at the end of class.

Day 2: Our Data Background Information The Crime Scene Official Police Report • CELENE ANDRADE was a 22 -year old female who graduated three months earlier from U. C. Berkeley with a degree in Psychology. She was single, but had been dating her boyfriend, MICHAEL RAPPUHN, off and on for two years. They planned to become engaged as soon as she completed her degree from Berkeley. They had different ideas about the role she would play in their new family. She had been accepted at Stanford Law School, and wished to pursue a career as an attorney. CELENE was preparing to start law school at the end of August. MICHAEL, conservative and jealous, insisted that she forgo a career to start a family. CELENE’s mother, LOURDES ANDRADE, had recently divorced and was opposed to marriage, she never had a good relationship with her daughter, and they barely had spoken to each other in almost two years. Following her graduation, CELENE had been living with her mother in Death Valley, while her father, Charles ANDRADE, had move to Atlanta, GA, after the divorce for business reasons. Her mother firmly believed that CELENE should marry her high school sweetheart, TONY SIMUNDSON. TONY was two years older than CELENE. He started attending U. C. Berkeley while CELENE was still in high school, and had since graduated and started medical school at U. C. San Francisco. TONY was also the brother of CELENE’s best friend from high school, HEATHER SIMUNDSON. CELENE and TONY dated during college, but broke up when he confessed he had cheated on her. CELENE started then dating MICHAEL, while TONY never recovered from the break up, being very unstable in both his studies and relationships. HEATHER attended a local college, while living with her parents in Death Valley, but never completed her degree. She and CELENE had not be in contact with each other for several days. • The following picture shows what the police found the morning after the crime was committed. LOURDES ANDRADE’s home is a large, two-story farmhouse with three bedrooms. The yard is very large, and the home is well-screened from the road. One ground-floor entrance is located at the front, as well as the back of the home. The locked, three-car garage held two vehicles: A silver 2003 Acura and a black 2002 Range Rover. Each of the vehicles was registered in California and contained no unusual signs of tampering, blood or other evidence. There were evident marks of tires different from those of the two vehicles in the drive way, but they belonged to a common type, so the police deduced it would not bring any relevant information for the case. LOURDES ANDRADE was caring for her elderly parents. She left for their home in San Mateo, CA, early Saturday (August 9) morning and was not scheduled to return to Death Valley until early Monday morning (August 11). CELENE had a brother that was home from college for the summer, he was away with friends on a camping trip to Patrick’s Point, several hours away. There are no others members of the household. The home’s silent alarm was triggered on Sunday, August 10, at 2 AM, many hours before the body was found. The Area alarm company called the police and Patrolmen Starsky and Hutch caught an intruder as he attempted to flee from the front door. The intruder was identified as KEVIN WALKER. Signs of attempted entry were found in the front door but the doors remained secure. No one answered the door or phone when the police called. The alarm company reset the system from the office and the police did not enter the home. • The body, identified as CELENE ANDRADE, was found in CELENE’s second story bedroom at 9 AM on Sunday, August 10 th. The victim was dressed in a new cotton bathrobe, later determined to be given to her by her mother the previous morning as a going away present. The victim wore no other clothing or shoes. A 22 caliber Colt revolver was found in the victim’s left hand. Fibers, other than cotton were found on the body and her hand. Two bullets had been fired from the gun. A single bullet was recovered, it had passed through the victim’s skull, entering through the right temple and exiting through the left occipital lobe of the brain case. The second bullet was never recovered. Powder remains were found on the left hand of the victim. The victim was pronounced dead at the scene. The coroner suggested that the time of death was at least six hours prior to the body being found. HEATHER SIMUNDSON discovered the body when she came to the house to take CELENE out for a going-away brunch prior to CELENE’s departure to law school. A suicide note was found on the dresser of the bedroom. Blood was found on the edge of the suicide note. Foreign hair was found on the body, robe, and suicide note. There was no sign of struggle, the bed was unmade, and one of the two bedroom windows was open, fingerprints were found on the window’s pane of the open window. Soil samples were found close to the victim. The Police inspected the backyard below the open window and concluded that there was no apparent access to the second story bedroom window from the ground floor.

Procedure Step 1 Step 2 Step 3 Step 4 Analyze your data from the crime scene. Collaborate a plan with your group. Make hypothesis. Analyze the evidence and suspect samples. Summarize and share your results with the class.

Day 3: Conclusion • Brief summary of what you discovered based on results. Answer simple and tough questions! • Indicate and explain whether or not the data supports your hypothesis. • Be prepared to share your findings as a group to the class. • Print out the results you found under the microscope that prove your suspect in guilty. Explain your findings in writing on the back. (Hand in at the end of class) • Remember to be sure! You do not want to send the wrong suspect to prison!

Question Examples • How did having concrete background knowledge about blood components and abnormalities aid you in this investigation? • What thing from the crime scene indicates that CELENE knew the person that committed the crime? EXPLAIN! • Mention 3 physical evidences from the crime scene that powerfully indicate CELENE did not commit suicide. EXPLAIN! • Reasons you believe led to the crime (why the culprit did it). EXPLAIN! • Which sample/s matches with the blood found in the crime scene? Briefly, explain why.

Ahead or Behind • Ahead: Students who may need a challenge can use the microscope to look at other evidence found at the crime scene such as fabrics, finger prints and hand writing. • Behind: Students who may struggle can be assisted by the teacher in small groups in order to set a common goal. The teacher can ask probing questions in order to focus the students in the right direction. • http: //jocha-biology. net/lab_exe/Crime%20 Scene. pdf
