Police say O'Fallon gunman had sexual assault record

O'FALLON — Gary Sheets, who is suspected of killing an ex-girlfriend at a medical clinic near St. Louis just days ago, has a sexual assault record, police and others say.

Sheets spent two years in prison for sexually assaulting a different girlfriend who had tried to break up with him.

The St. Louis Post-Dispatch reported today that the 45-year-old had served prison time for sexually assaulting a St. Louis woman he had dated and moved to Colorado with in 1998.

Sheets, a former blackjack dealer, returned to Missouri after his release from prison in 2000.

Last year, he met Jenenne Meadows, an avid poker player, at a bar and the two hit it off.

On Friday, police say, he killed Meadows after a standoff at St. John's Mercy Urgent Care Center in O'Fallon, where she was a lab technician.
