Investigators were expected to confer with prosecutors Monday afternoon or Tuesday on possible charges stemming from a rollover crash Sunday evening at 28th and Patee.

Sergeant Chris McBane of the St Joseph Police Department says his team’s investigation continues.

The Traffic Unit is investigating the possibility that excessive speed and alcohol may have played a role in the crash, and that the vehicle may have been reported stolen shortly before the 7:30 p.m. crash. Witnesses said the white truck driven by one of the motorists went airborne crossing over a hill near the crash site. The motorist sideswiped one parked car and then hit another vehicle nearly head on.

Police had to move witnesses from the immediate area of the crash for fear that some leaking gasoline might ignite.

Sgt. McBane would not release the name of that driver, who he said was admitted to Mosaic Life Care in serious condition. As we reported earlier, the truck crashed into a tree and the driver was ejected through the windshield. He has not been arrested, McBane said.

“Speed is definitely a factor in this, and we’re still looking into the whether alcohol played any factor or not,” McBane said in an interview.  “He sideswiped a parked vehicle and then hit the other car off-center but nearly head on.”

The other motorist was treated for minor injuries at Mosaic Life Care and released.

McBane says the investigation continues. He said they’re awaiting results from blood-alcohol tests and possible confirmation that the vehicle was reported stolen. His accident reconstruction team is also working on determining how fast the vehicle was driving at the time of the crash.
