3. The Crime Scene On Saturday, March 14th, the body of Miss Marie Rehr, World History teacher and volleyball coach at Bloom High School, was found. Her body was dumped on the Southeast entrance steps, near McCann gym, very close to her classroom. When her body was found, she was completely wet, and the coroner estimated that she had died within two hours of when the body was found.

4. The autopsy was immediately pursued and revealed large quantities of water in Miss Rehr’s lungs. The cause of death was listed by the coroner was drowning. The police concluded the Miss Rehr was killed and her body was transported to a different location.

5. Knowing where the drowning took place will help the police to possibly narrow their list of suspects. The problem is there are 10 bodies of water within a two-hour radius of where Miss Rehr’s corpse was found.

6. A chemical analysis of the water from the teacher’s lungs reflects abnormally high concentrations of phosphates. It is hoped that analysis of water from the possible drowning sites will pinpoint exactly where the teacher was drowned and thus provide a clue regarding her murder.
