Updated 7:45 p.m. to include word from neighbors, 2:15 a.m. Wednesday for details of Vegas Bray's arrest and 2:10 p.m. Wednesday to include the victim's name and history with Bray.
A man was shot multiple times and killed Tuesday afternoon in the Mariner's Point apartment complex, authorities said.
The San Diego County Sheriff's Department Homicide Unit was called to the scene near the Tijuana Estuary Visitor Center to investigate, said Lt. Dave Brown.
Imperial Beach deputies arrested 24-year-old Vegas Bray of San Diego for the shooting late Tuesday evening.
Bray has been charged with first degree murder, was booked shortly after midnight Wednesday and is currently being held at Las Colinas Detention Facility in Santee.
"Ms. Bray and the victim have had a past romantic relationship," said Lt. Glenn Giannantonio of the Homicide Unit in a statement.
NBC San Diego identified the victim as Victor Saucedo, a recently retired Navy veteran.
Friends told the television station that Bray vandalized Saucedo's car and apartment since the two broke up about a year ago, and that repeated calls to the sheriff's department weren't taken seriously because it was a woman harassing a man.
Sheriff officers could not be reached for additional comment regarding harassment at the time this story was published.
According to CBS 8, Bray is an employee at the Little Darlings strip club in Lemon Grove.
The victim has been described as a man in his late 20s or early 30s, but has not yet been identified by the sheriff's department.
Bray will be arraigned Friday at 1:30 p.m. at the South Bay Chula Vista courthouse.
Part of the apartment complex and a car on Caspian Way were surrounded by "DO NOT CROSS" tape.
Portions of the Tijuana Estuary Visitor Center parking lot were also cordoned off.
Greg Davis was watching TV when he heard what he thought were firecrackers, and now believes was the sound of nine shots being fired.
Davis lives in the building where the shooting took place, and moved to Imperial Beach from Harlem to be a Border Patrol agent.
"My son was near the window and the shots were really close, so I was scared a little bit for my little guy," he said about his 17-month-old Cameron. "Thank God the bullets didn't go through the wall."
Jesse Brothers, an aviation ordinanceman assigned to the USS Carl Vinson, and Jessica Pittman moved to Imperial Beach three months ago.
Both are from small towns near Dallas with populations of 2,000 or less, but now live across the parking lot from where the shooting occurred.
They didn't hear gunshots, but saw sheriff deputies begin to arrive in the area after 4 p.m. It's a quiet neighborhood, and Navy helicopters are typically the only loud sounds.
"As far as we could tell this was a safe place to live," Jesse said.
Jason Vetetoe is also in the Navy and moved into the Imperial Beach Gardens apartments across the street a little over a year ago.
"This is usually a pretty chill area. I've never seen nothing like this," he said.
