SEATAC, Wash. - A SeaTac family wants justice after someone shot their uncle as he was riding in a car last night.
King County Sheriff's investigators continue to look for clues in the shooting, which occurred at roughly 11:30 p.m. at Military Road South and South 140th Street.
A SeaTac family says the victim is their 18-year-old uncle, Adrian Beltran, who was visiting from California. He and four relatives were driving from a relative's house to a 7-Eleven.
Beltran's nephew says another driver flashed their brights, pulled up alongside and open fire.
"It happened so fast, he wasn't even here 48 hours," nephew Luis Gutierrez said." What happened to him was unbelievable."
Police say there are few leads - investigators don't have a motive, suspect description or even a description of the car.
Initially, Tukwila police got several calls from people saying they heard what sounded like fireworks or gunshots.
King County Sheriff's spokesman John Urquhart says several rounds were fired - police believe possibly from a rifle.
Family in the car rushed Beltran to the Highline emergency room, when he said he could feel his knees.
He later reportedly told his brother he was cold, moments before dying.
The family now wants help catching his killer.
"I don't know why he do it, what was going through his head. I want to know why he do it," Gutierrez said.
It took a couple of hours for police to find the crime scene. Once they did, they discovered at least a half dozen shell cases, but few clues.
"We can't find any incident of road rage, or something that would have precipitated this," said Urquhart. "So we don't know who the suspects are, we don't have description of the suspects' vehicle, and we don't have a motive for this shooting at this point."
The victim recently graduated from high school in California.
Beltran was the youngest of 11 children. He was younger than some of his own nieces and nephews. They say he was planning on working the summer here, and then attending a tech school in fall back in California, pursuing a career in law enforcement.
Urquhart said deputies don't believe the shooting was gang related and it appears to be random.That said, he added that doesn'tpreclude the fact that gang members may have been involved.
"It does seem senseless. It does seems random, and yet there's something here that causes people to do things we hope they wouldn't do," said Rev. Jan Bolerjack of Riverton Park United Methodist Church, located near the crime scene.
King County Sheriff's Office is asking for the public's help in gathering leads. If you have any information, contact the King County Sheriff's Office.
