I returned Tuesday morning to the Baldwin Park neighborhood where three people were killed, including an infant were killed Monday.

A man accused in the shooting, Roy Perez, 28, of Baldwin Park, is in custody.

The neighborhood was swarming with media, including Univision, Telemundo, Azteca America, KCBS, KCAL, KNBC, and KABC. The FOX 11 van carting Nichelle Turner was already packing their gear to head for the next story.

There are widely varying accounts of what happened. And no one can quite explain the sequence of events that ked to the killings and Perez’s arrest.

Brian Day and I listened to the incident as it unfolded on the newsroom scanner. Brian’s first words were, “I think this is going to get big. He bolted for the scene and arrived before backup units or the fire department. He reported that upon arrival he saw a man sitting on a porch wailing about his house his neighbors and begging the fire department for help.

Neighbors told a Univision reporter and our Bethania Palma that the man was in fact Perez. We are still trackign that down.

I also heard the story of a man named “Mario.” Mario was appraently moving from a house next door to where the shootings occurred. A relative said “Mario” witnessed much of the incident and saw Perez run from home to home in the neighborhood.

“Mario” apparently stayed outside the whole time the incident unfolded. “Mario’s” relatives said he wasn’t interviewed by the police and was allowed to leave before the investigation had been completed.

As you can see from the picture by Leo Jarzomb, the Los Angeles County Department of Coroner arrived roughly 12 hours after the killings. They are removing one of the three victims.

Perez was booked for murder and held without bail. Fatally wounded were Perezs mother, Alicia Rivera Perez, 47; along with Dalmy Perez De Mata, 31, and her daughter Briana Mata, said Craig Harvey of the coroners office.
