A trial is scheduled to get underway Wednesday in Mercer County for a Campbell man arrested in connection with a homicide in Farrell.

Twenty-eight-year-old Darrell Daurice Harrison Jr. is charged with first-degree murder for the shooting death of 21-year-old Jayson Burns of Sharon in April of last year.

Police say Harrison Jr., shot Burns along Roemer Avenue in Farrell. Burns died later at a hospital.

Harrison fled to Nebraska where local authorities arrested him.

Police say that during a fight with three men, Harrison pulled a gun and shot Burns.  

According to an affidavit, witnesses told police that Burns was shot while trying to escape as he was being assaulted on the ground. 

Troopers with Pennsylvania State Police collected surveillance video from a nearby business which captured the attack.
