HEMPSTEAD - ? Cops say they have found the men responsible for stabbing a teen to death on a Hempstead handball court three years ago.

Federal investigators say two MS-13 gang members stabbed Michael Alguera at Hempstead High School in 2008.

The indictment says David Valley and Louis Ruiz killed Alguera because they suspected the 15-year-old was in a rival gang.

Both Valley and Ruiz have been in jail since last year on other gang-related murder charges.
