Homicide detectives on Monday were trying to determine whether a man who was dropped off at a hospital with fatal gunshot wounds was involved in a shooting in La Mirada.

Los Angeles County sheriff's deputies responded to the 13400 block of Bona Vista Lane in La Mirada in response to reports of gunshots at 12:41 a.m.

When they arrived at the scene, deputies did not find any victims. Although a firearm and other evidence were discovered, it was not immediately clear if the man who was dropped off at the hospital was shot at the La Mirada location, the sheriff's department said.

HOMICIDE REPORT: A story for every victim

Authorities said the man, who was not immediately identified, was dropped off by an unknown person with fatal gunshot wounds.

In the last 12 months, there has been only one other homicide in the neighborhood, when 46-year-old Frank Mario Sainz was shot to death on Nov. 24 in the 14300 block of Alondra Boulevard.

And over the same time period, La Mirada has ranked as the 119th most deadly neighborhood out of Los Angeles County's 270 neighborhoods, according to a Los Angeles Times analysis of homicide data over that period.
