CASE STUDY QUESTION 2
SCENARIO: Three Chicago Socialites were murdered in Starved Rock State Park, Illinois. All
three women had fractured skulls. Their bodies, bound with twine, were found in a cave. Near
the bodies of the women, a bloodied tree limb was found and considered to be the murder
weapon. Because all three women had been staying at a nearby lodge, the staff of the lodge was
questioned. Chester Weger, a 21-year-old dishwasher at the lodge, was asked about a blood
stain on his coat. He said it was animal blood. He agreed to take a lie detector test and passed it.
He was requestioned and took a second lie detector test and passed it as well. The blood was
examined by the state crime lab and found to be animal blood as Weger had indicated at
questioning. The case reached a dead end.
Investigators decided to revisit the evidence. The rope used to bind the women was examined
more carefully. It was found to be 20-stranded twine sold only at Starved Rock State Park.
Identical twine was found in an area accessible to Weger. He again became a prime suspect. The
blood on his coat was re-examined by the FBI Crime Lab and found to be human and
compatible with the blood of one of the victims. Weger submitted to another lie detector test and
failed it. Weger was found guilty of the murder of one of the women, Lillian Oetting, and has
spent more than 45 years in prison. He petitioned the Governor of Illinois for clemency, saying
he was beaten and tortured into making the confession. He still maintains his innocence.
Instruction:
1. Identify the type of crime and the stages of the investigation in this case.
2. Discuss all of the biological evidence issues of the samples in this scenario. Explain a
possible issue/theory with sample taking as to why the blood on Weger’s shirt was first
considered to be animal blood. Also discuss further biological evidence or sample taking that
could have been considered.
3. Discuss the appropriate professionals that were/are suitable to examine this case.
4. Discuss the procedures of investigating this type of crime and if the investigators in the case
properly followed a proper procedure.
