Police in Pascagoula arrested 45 year old Mark Mouchett Saturday at his Pascagoula home in connection with the shooting death of 16 year old Robert Modica.
Detectives say Modica was hanging out with friends in this church parking lot on Halloween when a man drove up shot him in the head then drove off.
Police say they now believe that man is Mouchett.
Investigators say the shooting was a "random act of violence."
Modica's father, however, says he believes the motive is road rage.
Mouchett is in jail without bond.
