The personnel file for Minnesota State Patrol Trooper Shane Roper, who was charged Tuesday in a deadly crash in Rochester, Minn., reveals he had faced disciplinary action for four previous crashes before the fatal wreck.

The fatal three-vehicle crash happened near Apache Mall in Rochester, Minnesota, on May 18. 

Investigators say a Ford Focus was westbound on 12th Street Southwest when it turned south into the mall. The Focus was then struck by a Minnesota State Patrol cruiser that was driven by Roper, which was eastbound on the same street.

A Toyota RAV4 then ended up in the ditch after the Ford Focus was pushed into it.

A total of six people, including Roper, were injured in the crash. 

Roper's employment with the Minnesota State Patrol was terminated in September 2024, with agency leaders calling his actions "reckless."

Reviewing his behavior before the crash, investigators found several instances where Roper drove at high speeds in just the three hours before he crashed into the vehicle carrying Flores.

Roper was suspended for a day in two of the crashes and reprimanded for the other two.
