Clairton police anticipate a “lengthy” investigation into the alleged assault of a driver during a protest Monday relating to the acquittal of Michael Rosfeld.

The incident happened about 12:30 p.m. after some Clairton High School students walked out in protest of the verdict, which cleared Rosfeld of any crime in the June 2018 killing of Antwon Rose II.

Some participants allegedly assaulted the driver of a vehicle who came upon them.

“The investigation is anticipated to be lengthy as officers will be reviewing several videos,” said Chief Robert Hoffman. Those videos include police body-worn camera footage from multiple officers.

Investigators are also working to collect witness statements, he said.

Michelle Kenney, Rose’s mother, told Clairton students on Tuesday morning to stay in school, according to Tribune-Review news partner WPXI-TV.

“When I saw what happened when you guys were marching my heart was breaking,” the TV station reported Kenney telling the students. “It was breaking because I knew it was a situation that could escalate from zero to 100 real quick.”

Kenney sent a similar message to students at Woodland Hills, where her son was a student, on Monday morning.

The department will work with the Allegheny County District Attorney’s Office to file charges, Hoffman said.
