The two young men were gunned down last December on the 7000 block of Hazeltine Avenue.
"They were on their way to a studio Kevin had where they could play guitars and not disturb the community from the soundproof room," said LAPD Captain Gary Miller. "They were good young men, trying to do the right things in their lives, trying to be successful."
Police say Deville and Garcia were not gang members. They were best friends. Garcia was a father, and they both leave behind large families and many friends who are still hoping for justice.
"It's extremely hard for me to be here without them," said Yanina Cortez. "But I know they are with us, and they would like for me to beg you: Please, if anyone saw anything, please come forward."
Councilwoman Wendy Greuel is sponsoring a $25,000 reward to entice someone who knows something about the double murder to speak up.
Police have run out of leads, but they believe that some apartment residents may be holding back information. Deville's mother is pleading for them to find the courage to make that phone call.
"A lot of times people don't want to come forward because of fear of retaliation, because you have to live in this area, and it is a scary thing. But knowing that these people, or this person, that is responsible for this is still roaming around, should scare you even more," said Kevin Deville's mother.
