Tilmon Charles Golphin, 19 and his brother Kevin Salvador Golphin, 17, are accused of killing Highway Patrol Trooper Ed Lowry and Cumberland County Sheriff's Deputy David Hathcock during a traffic stop on Interstate 95 last fall.
A judge is deciding whether to try the brothers together or separately. More pre-trial motions are expected the rest of the week.
The Golphin brothers each face the death penalty.
