Who Needs Surveillance Cameras When You Have Webcams And MySpace?

Come on — seasoned criminals know to keep a low profile online:

A photograph lifted from MySpace.com and handed to a grieving relative of a victim in Sunday’s fatal subway shooting led to the arrest yesterday of a 16-year-old Bronx boy, police sources said.

“This is the kid who shot your nephew,” a man unknown to the family told the aunt of Rayquon Story, 19, who was killed early Sunday on a parked No. 5 train in Eastchester, the Bronx, police sources said.

After handing her the photo, the tipster went on to tell the aunt that the suspect, identified by police as Robert Denis, lives in Co-op City.

She turned the photo over to detectives, who then spoke to Co-op City security. They recognized the teenager and he was taken into custody.

Denis is accused of squeezing off five rounds during a 2:30 a.m. confrontation at the Dyre Ave. and E. 233rd St. subway station, striking four people, including Story, cops said.

He made a videotaped statement at the 47th Precinct stationhouse, and was awaiting arraignment at Bronx Criminal Court on charges of murder, attempted murder, manslaughter and criminal possession of a weapon last night.
