Here's the homicide locations that I've collected for the month of May and a little of June. Hopefully you'll find the west LA County data (from the LA Times homicide map) a useful addition.
Pomona saw two homicides in the month of May. Roberta Romero, a 24 year-old resident of West Covina, was found in the street at approximately 5:30 AM after being shot by to males, one from Covina and the other from Azusa. Both men have been arrested. Based on the limited reporting it appears that the victim was simply driven to this location before being shot. If anyone can add any further clarifications please do. The second homicide appears to be hit-and-run victim who was struck while a father was attempting to kidnap his child and the child's mother. The child and mother were found safe the next day, but I have no information regarding the status of the suspect.
