THE FACTS OF THE CASE
Centerville police discovered the bodies of a 36-year-old white male (later identified as Gaven Brooks) in a field about 20 miles north of town. Mr. Brooks’s body was discovered at 7:30 P.M. on Friday, October 11. He was found lying face up on a yellow, queen-size sheet. According to autopsy reports, one fatal gunshot to the back of the head ended Mr. Brooks’s life. Scientists estimate that death occurred at about 4:20 P.M. As investigators scanned the crime scene, they made the following notes:
- Paper plates filled with partially eaten fried chicken, deviled eggs, potato salad, and chocolate cake were located near Mr. Brooks’s body.
- An open bottle of red wine and two partially filled glasses of wine were found next to the yellow sheet.
- A recently smoked cigarette butt was found near the sheet.
- Shoeprints from the road to the field were those of a male, size 10, and a female, size 5. The only shoeprints from the field back to the road were those of a female, size 5.
- Car tracks of the same wheel base and tread pattern as Mr. Brooks’s automobile were found at the road. The car was not found at the scene.
- Mr. Brooks’s car was found abandoned in an empty parking lot in downtown Centerville.

After questioning family and friends, it was discovered that the deceased had frequent social outings with six women who live in or near Centerville.
