The Latest: Black teen's family says officer was aggressive

The Latest on the homicide trial of a white Pennsylvania police officer in the shooting of an unarmed black 17-year-old (all times local):

9:10 a.m.

Relatives of Antwon Rose say they are "seeking the justice they so deserve" as a white police officer goes on trial in the fatal shooting of the unarmed black teenager.

A statement released Tuesday by family attorney Fred Rabner says Michael Rosfeld was "hair-triggered" and "overly aggressive" when he killed the 17-year-old high school student during a traffic stop in East Pittsburgh last year.

Rosfeld is charged with homicide. His lawyers have said he thought someone in the unlicensed taxicab that Rose was riding in had pulled a gun on him.

Rabner represents the family in a wrongful death suit against Rosfeld, the borough and its mayor and police chief.

The family statement says Rosfeld's service weapon "left an irreparable hole in their collective souls."

1:30 a.m.

A white Pennsylvania police officer who shot and killed an unarmed black teenager last year is headed to trial in a case that could put him behind bars for life.

Lawyers for 30-year-old former East Pittsburgh Police Officer Michael Rosfeld are expected to argue that the June shooting of Antwon Rose II was justified.

The trial starts Tuesday morning and is expected to last about a week.

Rosfeld is charged with criminal homicide for shooting 17-year-old Rose in the face, elbow and back.

Authorities have said Rose had an empty ammunition clip in his pants when he was killed but not a weapon.

Police say Rosfeld made conflicting statements, including that he saw something in Rose's hand that Rosfeld thought was a gun.
