Devastated family members say Khaimov was on the ground, bleeding and crying for help for over an hour before someone finally called 911.
"Nobody's blaming anybody, but everybody has to wake up at some point and stand up for one another and stop caring about one's own well-being," said the victim's niece Angela Ibragimova.
The victim's family is offering a reward for information leading to the arrest of his killer. Police say they have no motive and no suspects. If you have any information, you are asked to call the LAPD at (877) LAW-FULL (877-529-3855).
