Three people are dead and a fourth person was wounded in a shooting near Lacey that might have happened several hours before it was reported to police.

Investigators later said they found a half pound of methamphetamine in the travel trailer where the bodies were found. Heroin, several thousand dollars and several guns also were found.

The murder weapon has not been found.

The Thurston County Sheriff’s Office said there was a drug operation on the property but the motive for the shootings isn’t known.

Dispatchers received a 911 call around 5:15 a.m. Wednesday from a man stating he had been shot and his friends were dead, according to Chief Dave Pearsall with the Thurston County Sheriff’s Office.

The caller couldn’t give an exact location where he was, but deputies eventually tracked him down to the 500 block of Dutterow Road, where they found the man on the ground with a gunshot wound to his stomach. He was rushed to St. Peter’s Hospital in Olympia where officials said he was in surgery but in stable condition.

Deputies searched the property and found the bodies of two men and a woman who had been fatally shot inside the travel trailer, Pearsall said.

The slain victims are a 31-year-old woman from Lacey, a 28-year-old man from Olympia and a 34-year-old man from Elma. The two men were shot in the head and the woman in the back.

A 30-year-old Olympia man is in the hospital. He is reported to be out of surgery and in stable condition.

Pearsall didn’t have any further details on the motive for the shooting or if any suspects were in custody.

Neighbor Jan Phipps told she actually heard three shots fired around 8:45 p.m. Tuesday.

“My boyfriend (and I) were standing out here and we heard three gunshots,” Phipps said. “It was pop, pop, pop.”

She says she didn’t hear any screams or noises before the shots and admits she didn’t think to call 911.

“A couple of years ago there were some pretty bad people over there and they used to shoot their guns off and they liked to shoot fireworks off,” Phipps said.

In the meantime, as investigators try to sort out whether the gunman is still on the loose or among the victims, they’re asking for help from the public.

“We’re asking the public if they hear or see anything suspicious to give us a call,” Pearsall said.
