Alfonzo Landa, 17, a reputed associate of the Blythe Street gang, was also charged with six counts of attempted murder and attempted carjacking, the Los Angeles Times reported. Jane Robison, a spokeswoman for the Los Angeles County District Attorney, said Landa has been charged as an adult and is being held in lieu of $9 million bail.
Andrew Garcia, 4 months old, was shot in late September as his parents, Marlene Ramirez and Frank Garcia, left a friend's baptismal party. Witnesses said Garcia was talking to two friends on the street when they were approached by two men who asked them where they were from and opened fire when they responded "Barrio Van Nuys."
Investigators say the baby is the latest of many victims of a feud between the Blythe Street and Barrio Van Nuys gangs that has endured for years.
Investigators were seeking a second suspect in the killing.
