A convicted killer has been charged with murdering three men in a Maryland shooting in 2003.

Prince George's County police announced Thursday that 29-year-old Moises Medina is being charged with three counts of first-degree murder for the 2003 shooting at the Stardust Inn in Landover Hills.

Medina had been serving a sentence for an unrelated homicide.

After a six-year investigation, Medina became a suspect in the motel shooting. He is charged with killing Noe Ornelas-Cruz and Robert Roman Jr., both of Lanham, and Francisco Javier Ornelas of Alexandria, Virginia in an April 8, 2003 shooting.
