Frederick Gray is on trial for the attempted murder of Wilmington Police Patrolman Justin Wilkers last year.
Wilkers, a 3-year veteran of the force, was shot in the face in February 2013 after a routine traffic stop in the Southbridge section.
The partner of Officer Wilkers took the stand Wednesday, and a second officer who was at the scene is expected to testify on Thursday.
Frederick Gray is facing charges of attempted murder, but his lawyer says he was misidentified, and someone else was the triggerman.
