The city of Los Angeles has already offered a reward for the outstanding suspect in the case of a murdered 4-month-old infant. Now, the Department of Alcohol, Tobacco and Firearms is putting up a reward as well.

The ATF and the LAPD are working together to find 23-year-old Ricardo Hernandez. They are asking for the public's help and they are hoping that a $75,000 reward will lead to Hernandez's arrest.

It was Sept. 27 when 4-month-old Andrew Garcia was the victim of gang gunfire.

The LAPD says Hernandez, a known gang member, and another associate approached a group on Kittridge Street and asked them where they were from.

Baby Garcia was in the car being fed. According to the LAPD, Hernandez opened fire with a shot gun six times. Garcia was hit in the head, and his father was wounded along with somebody else.

"If Ricardo the suspect is listening, turn yourself in and do the right thing, because the LAPD and the federal government and some other federal law enforcement agencies, we will get you at some point and time, we will get you. And if somebody is harboring him, I also urge you to do the right thing and turn in Ricardo because he is out there somewhere," said ATF agent John Torres.

"Our interest in the Los Angeles Police Department is to find the information of where this individual is at," said Deputy Chief Michel Moore. "We ask the public to reflect upon their feeling of what position they would be in if they had lost a 4-month-old child, being cradled in a woman's arms, shot and killed on the street for no reason. Absolutely just senseless violence."

If you have any information on Hernandez's whereabouts, you are urged to contact the LAPD at (877) 527-3247. Investigators believe that Hernandez still may be in the San Fernando Valley area.

According to police, a 17-year-old who was with Hernandez has already been arrested and is facing a murder charge.
