Laurence Marcellus Marshall IV, 20, of Montgomery Village, the suspect in the July 5 fatal shooting of Cederic Allen Warner, 40, of Silver Spring, turned himself in Thursday at the 6th District Station in Gaithersburg, Montgomery County Police said.

Police announced Tuesday that they issued an arrest warrant for Marshall, who was charged with first-degree murder. Police offered a $10,000 reward for information leading to his arrest.

Marshall shot and killed Warner on July 5 in the 11500 block of Lockwood Drive in Silver Spring, police allege.

Police said they responded to a report of a shooting that night around 9:51, locating Warner near the Vista at White Oak Apartments, close to both Old Columbia Pike and New Hampshire Avenue.

Warner was suffering from apparent gunshot wounds, and while they provided life-saving measures until Montgomery County Fire and Rescue Services arrived, he was pronounced dead at the scene, according to police.


Marshall was transported to the Central Processing Unit, where he awaits a bond hearing, police said.
