High school student Jason Nguyen was discovered in his home by a family member just before 3 p.m. on Sunday.
Const. Brian Montague says the teen had severe injuries and rushed to a nearby children's hospital, but he died on the operating table.
Montague says the killing does not appear random, but declined to provide details about suspects or whether weapons were involved.
Investigators are now attempting to create a suspect profile by canvassing the teen's family, associates and friends.
Montague says police don't believe the public is at risk, though no arrests have been made.
