WSB-TV has learned that Milton, Georgia police are reopening the investigation of a different man's death who once dated a high-priced call girl,  Alix Tichelman who is accused of injecting a Google executive Forrest Hayes with heroin and leaving him for dead.

Two months before Hayes' death, Tichelman had been arrested by Milton, Georgia police for biting her then-boyfriend, 53-year-old Dean Riopelle. 

About two weeks after Tichelman was arrested for biting Riopelle, Riopelle died.

McCarty says a medical examiner concluded Riopelle did in fact die of an overdose. However, he says investigators want to take a second look to make sure they did not miss anything.

Tichelman is charged with manslaughter in the November death of Google executive Forrest Hayes.
