The suspects are believed to be Paul Capetillo, 18, and Bulmaro Aguiniga, 21.
Both are known gang members with ties to the Central Valley, Southern California and Mexico and should be considered dangerous and possibly armed, police said.
Gonzalez, a freshman at Abraham Lincoln High School, was shot in front of his cousin's home in the 400 block of Auzerais Avenue at about 1:05 a.m. on Jan. 1.
Detectives say Capetillo and Aguiniga have fled from San Jose to avoid being arrested. Felony warrants have been filed for their arrests and detectives are reminding anyone who may be associated with the suspects that aiding or abetting them in their attempt to avoid capture is against the law.
Capetillo is about 5 feet 2 inches tall and 120 pounds, with black hair and brown eyes. He has "WS" tattooed on his left arm.
Aguiniga is about 5 feet 9 inches tall and 180 pounds, with brown hair and brown eyes. He has a tattoo on his chest reading "WSM."
Anyone with information regarding the whereabouts of either suspect should call 911. Anyone with information regarding the murder is asked to contact Detective William Hoyt at (408) 277-5283.
