WEST VALINDA — Authorities Thursday released the name of a 27-year-old man who died earlier this week after being wounded in a weekend shooting outside a small birthday celebration at his home.

Abelardo Madrid was pronounced dead at 4:30 p.m. Monday at Los Angeles County-USC Medical Center, according to Los Angeles County sheriff’s and coroner’s officials.

Madrid had been hospitalized in “extremely critical condition” since Saturday’s shooting, which took place shortly after 10 p.m. Saturday in the 1300 block Evanwood Avenue, in the unincorporated county area of West Valinda, according to Lt. David Dolson of the Los Angeles County Sheriff’s Homicide Bureau.

Madrid was standing in a residential driveway when a car and an SUV pulled up, investigators said. One attacker exited one of the cars and briefly confronted Madrid before opening fire.

“Something was said that we don’t know at this point,” Detective Kevin Acebedo said. “There were gunshots immediately after.”

Madrid appeared to have been shot twice, including at least one wound to the head, according to sheriff’s and coroner’s officials.

Investigators said the shooting initially appeared to be gang-related.

Acevedo said there were no indications Madrid had gang ties, however, “We do believe the suspects were probably gang members.”

There was a small family gathering at the home at the time of the shooting to celebrate the birthday of an adult, detectives said.

Officials described the involved vehicles as a silver SUV and a compact car, possibly white in color. No description of the suspects themselves was available.

Acevedo asked that anyone with information contact the Sheriff’s Homicide Bureau at 323-890-5500. Tips can can also be submitted anonymously to L.A. Crime Stoppers at 800-222-8477.
