That was fast … prosecutors in Los Angeles County say they’ve charged three men with murder in the fatal shooting of Maria De La Rosa, a singer who went by the stage name DELAROSA.

Los Angeles County District Attorney Nathan Hochman says the alleged killers in the “ambush-style attack” are 27-year-old Francisco Otilio Gaytan, 27-year-old Benny LiconGomez, and 21-year-old Eduardo Lopez … prosecutors say they are all from Northridge, where the shooting occurred early Saturday morning … and each has been charged with one felony count of murder and two felony counts of attempted second-degree robbery.

Hochman says the men allegedly approached a parked car shortly before 1:25 AM on Nov. 22 on Bryant Street in Northridge … they demanded money and then opened fire, killing DELAROSA. She was in the car with two friends, who were not harmed.

We broke the story … dispatch audio indicated DELAROSA was shot in the abdomen.

Hochman says … “This was a ruthless and targeted attack that stole the life of a young woman and artist and inflicted profound lifelong trauma on her family and the two survivors.”

The D.A. says Gaytan’s bail has been set at $2.18 million … and LiconGomez’s bail is set at $2.28 million. Whenever Lopez is arrested, Hochman says his bail will be $2.205 million.
