A father of three was shot dead in California just days before Christmas after he and a group of neighbors confronted a man who they saw breaking into cars in their neighborhood.

Joey Casias, 38, was trying to break up a fight Tuesday night between some of his neighbors who confronted the suspect, his mother, Lydia Casias, told FOX11 Los Angeles.

"My granddaughter, when we put her to bed, she said, ‘Please don’t tell me that my daddy is not going to be here for Christmas,’" Lydia Casias told the station. "And that broke my heart."

Police said the shooting happened around 11 p.m. in the 1800 block of East Covina Blvd. in Covina, a city about 22 miles east of Los Angeles. The suspect fled the scene and set off a police search.

Police said officers were responding to a robbery in progress call when they arrived to find Casias dead.

On Wednesday, officers acted on a tip and located a man, identified as 34-year-old Trevor Thompson, who was wanted in connection to the shooting, police said in a statement. Thompson was found at an apartment complex in Covina, where he barricaded himself inside the indoor patio.

Lydia Casias described her son as "wonderful," saying that he took care of her after her husband died 18 years ago. She said that she’s "seen these reports many times on the news," and they’ve always broken her heart.

"And now I’m broke," she told the station.

A GoFundMe page set up for Casias’ family described him as the type of man "that this world needs more of."
