William “Billy” Peters, his fiancee, mother, brother and friends had gone out to the Acropolis bar Saturday night in southeast Portland after celebrating his 4-year-old daughter’s birthday earlier that day.

Others in the group had already left when Peters and a friend — Adam David-Lawrence Arrambide, of La Pine — were fatally shot in the strip club’s parking lot as they were trying to leave.

“They went out for a quick drink and never came home,” said Brandon Krupp, a friend of Peters’.

Portland police confirmed Tuesday that Peters, 40, was shot and killed outside the Acropolis in the 8300 block of SE McLoughlin Boulevard. Police were called at 11:30 p.m. to the club on a report of two people shot.

Peters died at the scene, police said. Arrambide, 36, died Sunday at a hospital.

No arrests have been made in the double homicide. It’s not clear what led up to the shooting.

Peters owned and managed a print shop called 503print and had just opened a new warehouse in the last couple of months in the Milwaukie area, friends said.

They described him as a dedicated father who worked hard to establish and build his business and noted his passion for sand dune riding.

“He was just everybody’s friend,” said friend Tiara Champ. “He put his blood, sweat and tears into his business. We’re going to make sure it lives on for him.”

Krupp knew Peters from the sand dune community.

Krupp had started a Facebook group for dune riders called Sand Adiks five years ago. He said Peters printed clothing, stickers, hats, hoodies and jackets for the dune riding community.

Some rode four-wheelers or dirt bikes and others, like Peters, drove off-road cars called side-by-sides, Krupp said.

“He was very outgoing, and every time he showed up to ride, he gave free gear to everyone. He’d bring merchandise out there and hand it out to promote his shop,” Krupp recalled. “He’d go out there with a smile, and say, ‘Here’s a 503print shirt’ for you all, and hand them out for free.’”

Nick Proto met Peters while camping by the dunes at Sand Lake Recreation Area a couple of years ago. Peters needed a part for his off-road sand buggy and Proto helped him out, and they remained friends since.

Peters often hosted barbecues at his home — always steak, shrimp and salad, Proto said.

“That man did nothing but smile and try to make sure everyone was as happy as he was,” Proto said. “It’s unbelievable how he’d touch people. You’d know him for two days and think that’s my best friend.”

He said Peters started his print business out of his garage, “and kept going at it and kept going at it,” and is now fairly well-known in the city. His business sold screen prints, vehicle graphics, banners, stickers and clothing prints.

“All he ever did was work and barbecue and ride. He was really active. Real gung-ho. He never slowed down,” Proto said. “It breaks my heart.”

Peters’ fiancee, Melissa Moore, and friends went Monday to the scene of the shooting to grieve.

“This hurts so bad,” Moore wrote on Facebook.

She said she saw a pool of Peters’ blood in the club’s parking lot. “I had to put his blood on my shirt and take it home with me,” she wrote.

Moore also wrote that she’s struggling with anger. “People are being gun downed like a game by all those running wild because they have nothing to fear, we don’t have the police force or funding to fight this violence,” she wrote on Facebook.

Peters’ friends have planned a memorial dune ride in his memory at Sand Lake Recreation Area at noon on Saturday.
