Arrest made in fatal shooting of 3, including father and 9-year-old son, in San Bernardino

SAN BERNARDINO, Calif. (KABC) -- An arrest has been made in a triple shooting outside a San Bernardino liquor store that left three people dead last week, including a father and his 9-year-old son, police said.

San Bernardino police said they arrested 26-year-old Trayvon Eshawn Brown of Rialto for the triple murder.

The shooting occurred outside a liquor store Friday, July 8 around 9:15 p.m.

Authorities said Brown waited outside the business for Travon Lamar Williams, Williams' 9-year-old son also named Travon, and family friend Samathy Mahan, 25. When the three exited the store, Brown shot them in an ambush-style attack, police said.

Investigators said Mahan appeared to be the intended target, saying Brown and Mahan had a prior violent encounter over a woman that led up to the shooting.

Law enforcement said Brown has a long criminal history, but he was out on parole as a result of California's realignment laws.

San Bernardino police Chief Jarrod Burguan said this is a reoccurring pattern.

"It's very, very frustrating for folks that think that we've done all the things from a police stand point to have prevented these things in the past, and yet we still have these things happening on the streets," Burguan said.

Williams senior did not have a criminal background, and his family was once again reeling from tragedy.

Ten years ago, Williams' twin brother Traveil was shot and killed over his cellphone.

"The only solace that we have is that he is with his twin brother now, and that his son is with him like he always wanted to be - with his dad," said Claudia Oakenfull, the victim's aunt.

Williams left behind three daughters, and his partner of eight years was unable to explain the loss to her two girls.

"It is shocking for someone that's not gang-affiliated, for someone who is so happy and smiles all the time, and someone just take him away like that," said girlfriend Shemica Lucas.

Police said Brown is not cooperating and refused to give a statement to investigators.

Because he is a parolee, he was not eligible for bail.

A GoFundMe account was set up to help with funeral costs for Williams and his son.
