Police arrested a Manhattan teen this morning on murder charges after he allegedly gunned down three men in West Philadelphia just before Christmas.

Marco Joaquin, 18, was charged with two counts of murder in the Dec. 22 deaths of Anthony Fletcher, 33, and Dwayne Page, 29, of Reedland Street near 65th in Southwest Philadelphia, said Officer Tanya Little, a police spokeswoman. Joaquin had been listed as one of the Police Department's "most-wanted fugitives."

Police found the three victims inside Fletcher's apartment on Chester Avenue near 46th Street about 10:30 p.m. that night. Fletcher, who had been shot in the head, died on the scene, while the second man died of a gunshot wound to the chest at the Hospital of the University of Pennsylvania. The third victim, 28, survived despite being shot in the chest and head, Little said.

Investigators listed the motive as drugs, Little added.
