Craig Patterson hearing in Julian Dawkins murder case

ALEXANDRIA, Va. (WJLA) An Arlington County Sheriff's deputy charged with first-degree murder has a preliminary hearing Tuesday.

Craig Patterson is accused of killing Julian Dawkins back in May. Police say the two got into an argument near Dawkins' home in Alexandria. Investigators believe at some point Patterson left, got his gun, and shot Dawkins in the chest.

Patterson's lawyers say he acted in self defense. He's been held without bond since the shooting.
