LOS ANGELES (CBS) — Police on Monday said an arrest could be imminent in the fatal shooting of a one-year-old baby in Watts.

KNX 1070′s Claudia Peschiutta reports detectives believe they are close to identifying a suspect in last week’s shooting.

“The investigation is actually moving along pretty well,” said LAPD Detective Jim Vena, who said the prospect of naming the person responsible for gunning down Angel Cortez in the arms of his 24-year-old father Mauro on June 4 looked “real promising”.

“I don’t want to say it’s been ID’d yet, but it is moving in the right direction,” he added.

A suspect described as a 15- to 17-year-old boy riding a bicycle opened fire on Cortez in the 10500 block of Hickory Street at 7:49 p.m. Monday, according to police.

Angel died shortly after undergoing surgery on his abdomen, while his dad, who was shot in the shoulder, was released from the hospital Tuesday.

The city of Los Angeles first offered a $50,000 reward for information leading to the person responsible for the murder and were soon joined by an additional $50,000 put up by the Los Angeles Kings and AEG.
