PONTIAC (WWJ) – Police say a 72-year-old Pontiac resident died shortly after having sex with a local prostitute.

Investigators said the man was driving with the sex-worker on Woodward near Whittemore Street Saturday when he suddenly slumped over the wheel causing the vehicle to stop in the middle of the roadway.

The man was taken to Pontiac Osteopathic Hospital where he was later pronounced dead.

Authorities said the prostitute was not immediately forthcoming with information about events leading up to the incident.

“We obviously investigated the death and the circumstances around the death and determined what had happened and, ultimately, the woman was arrested on an outstanding warrant,” Bouchard said.

She eventually reported that the victim picked her up at her Pontiac residence earlier in the day. They then drove to another Pontiac residence where they had consensual sex. At that time the man had some trouble breathing and told her he had an asthmatic condition.

The man and the woman’s identities have not yet been released.
