The East Pittsburgh police officer who fatally shot 17-year-old Antwon Rose II on Tuesday was recently identified as Michael H. Rosfeld. Once Rosfeld’s name became public knowledge, rumors surrounding the 30-year-old’s alleged violent history as an officer were trending on Twitter.

According to the Pittsburgh Post-Gazette, Rosfeld left his last job at the University of Pittsburgh police after authorities discovered discrepancies between the officer’s sworn statement and evidence in an arrest. In January, Officer Rosfeld left the university police department after the Allegheny County District Attorney’s office withdrew all charges he’d pressed against three men accused of fighting in a bar.

In December, Rosfeld wrote a criminal complaint accusing three men — Timothy Riley, 24, Jacob Schilling, 24, and Daniel Humphrey, 26, — of "extremely belligerent yelling" at the officer, the owner of a bar where they were kicked out and a bar employee.

Although the men were charged with simple assault, defiant trespass, disorderly conduct and public drunkenness, the charges were dropped on Dec. 21 due to inconsistencies in Rosfeld’s report.

“We didn’t think we could sustain our burden of proof based on the evidence available,” district attorney spokesman Mike Manko told the Post-Gazette.
