Two men were killed by an unidentified gunman last week while sitting in their car in the Southcenter Mall parking lot.

On Sept. 12, a woman in the parking lot heard gunshots around 4:35 p.m. and turned to see a man who appeared to be in his 40s standing next to a car.

She later told Tukwila police that the two men in the car were slumped over as the suspect walked calmly back to his car and drove away.

When officers arrived at the scene, they found 17-year-old Ivan Payan Rojas dead and 27-year-old Alfonso R. Ayala critically injured from gunshot wounds.

Ayala was taken to Harborview Medical Center where he died Sept. 13.

Police had not determined a motive behind the shootings late last week, but were able to release a sketch of the man believed to be the shooter.

He is described as white, in his 40s, 5 feet 10 inches to 6 feet tall, between 180 and 200 pounds, with brown hair and a bushy mustache.

His car is described as tan or bronze, two-door-sporty, with a hood scoop and rear spoiler.

Anyone with information about this double homicide is asked to call 206-431-3689.

Three days later, a second shooting in Tukwila sent a 22-year-old man to Harborview Medical Center with bullet wounds in his torso and thigh.

The shooting occurred around 10:30 p.m. Sept. 15 in the parking lot outside the Regal Cinema, 5910 S. 180th St.

After he was shot, the victim went inside the theater and called 9-1-1. He was later listed in stable condition.

The suspects were described as three Asian males between 18 and 22 years old.
