ST. LOUIS PARK — A man with a history of driving under the influence was charged with criminal vehicular homicide Tuesday days after he rammed his car through a Minnesota restaurant’s outdoor patio where a group of medical professionals were celebrating after work, killing two people and injuring nine.

Steven Frane Bailey, 56, faces two counts of criminal vehicular homicide for intoxication and negligence, and nine counts of criminal vehicular injury. The number of charges could rise if investigators identify more victims, Hennepin County Attorney Mary Moriarty said at a news conference Tuesday.

A 30-year-old mother of three who worked as a server at the Park Tavern in St. Louis Park and a medical staffer at a nearby hospital who was beloved by his colleagues both died after Bailey said he hit the gas pedal instead of his brakes. Nine others were injured in the deadly crash, which left a Minneapolis suburb in shock that a pleasant evening dining outside could end in tragedy.

“Bailey could have simply decided to stay home or take a Lyft rather than driving while intoxicated,” Moriarty said. “This tragedy killed two people and injured several others, and it was entirely avoidable.”

Moriarty did not know whether Bailey had retained an attorney on Tuesday. Calls to him and a family member, as well as an attorney who represented him in a previous case, were not returned Tuesday.

Surveillance footage captured Bailey pulling into the Park Tavern parking lot, driving past an open parking spot and hitting a parked car when he tried to back into that spot, a criminal complaint said. He then pulled out and accelerated toward the patio, barreling through a metal fence into a crowded area where patrons, restaurant staff and several children were gathered, court records show.

His gray BMW came to an abrupt stop after he hit several rocks on the patio. The server who died, Kristina Folkerts, was pinned under the car until police officers lifted it off her. She died at the scene. Gabe Harvey, who was at the restaurant celebrating with several colleagues from Methodist Hospital, was hit and pronounced dead later at a different medical facility.

Tables, chairs, beer glasses and furniture were strewn about over an artificial grass turf mat at the chaotic scene.

When police officers approached Bailey’s vehicle they heard him talking on the phone, prosecutors said. They reported hearing him say, “I hit the gas instead of the brake and went right through a thing” and “I’m probably going to jail.”
