Auburn-Federal Way Man Suspect in Murder

1/ On May 9, 2026, a gunman fatally shot 32-year-old Sean Walton at Lowman Beach Park's beer garden in Seattle's Magnolia neighborhood during a crowded beach party. Witnesses described hearing multiple gunshots around 8:30 p.m., with Walton collapsing near the bar area. Seattle Police arrived within minutes, but the shooter fled on foot before vanishing into the park's wooded trails (; ). 2/ The park, run by Seattle Parks and Recreation, hosts popular summer events like the "Beach Beer Garden" series, drawing hundreds for drinks, live music, and sunset views of Puget Sound. That night featured a DJ set and food trucks, with attendance estimated at 200-300 people by event organizers. No other injuries were reported, though panicked crowds scattered as shots rang out (; ). 3/ Who is the suspect? 28-year-old Jamal "Jay" Carter, a resident of the Auburn-Federal Way area in South King County, roughly 25 miles south of Seattle. Carter has no prior felony record in Washington state databases but was named in a 2024 misdemeanor assault case that was dropped, per court records. He worked as a delivery driver for a local logistics firm until last month (; ). 4/ A key witness, who knew Carter from Federal Way high school circles, told police she picked him up near S 320th St. in Federal Way around 6 p.m. on May 9. Surveillance video from a nearby gas station corroborates this, showing Carter entering her silver Honda Civic. The pair drove north on I-5 toward Seattle, arriving at Lowman Beach about 90 minutes later. The witness claims she waited in the car while Carter entered the beer garden, returning 20 minutes later "visibly agitated" before they sped off (; ). 5/ Carter turned himself in to King County Prosecutor's Office on May 12 via his attorney, Michael Ruiz of Ruiz & Associates in Tacoma. He was booked into King County Jail on suspicion of first-degree murder and drive-by shooting, then released on $250,000 bail the next day. Prosecutors have 72 hours from surrender to file charges, per Washington law, but as of May 15, no formal charges appear in court dockets (; ). 6/ What happened inside the beer garden? Witness statements and park CCTV show an argument escalating between Walton and Carter near the outdoor taps. Walton, a Seattle-based mechanic originally from Tacoma, reportedly shoved Carter after words were exchanged over a spilled drink. Carter then pulled a 9mm Glock from his waistband, firing three rounds—two hitting Walton in the chest and one grazing a picnic table. Ballistics matched casings recovered at the scene to the weapon later found in Carter's Federal Way apartment, per search warrant returns (; ). 7/ Motive remains unclear. Investigators cite "personal dispute" in affidavits, possibly linked to a woman both men knew from Federal Way nightlife scenes. Walton's phone records show texts with a mutual acquaintance hours before the shooting, but no direct messages between victims and suspect. SPD homicide detectives are reviewing social media for gang ties, though neither man has documented affiliations with groups like the Crips or Bloods subsets in South King County (; ). 8/ Walton's family launched verified GoFundMe and MealTrain campaigns on May 10, raising $28,000 by May 15 for funeral costs and lost wages—his wife is pregnant with their second child. Seattle Mayor Bruce Harrell called the shooting "senseless violence" at a May 13 presser, pledging $50,000 in city rewards for additional tips. Crime in Magnolia rose 15% YTD, per SPD stats, amid post-pandemic park crowding (; ). 9/ Next steps: King County prosecutors must decide on charges by May 15 evening. If filed, arraignment is set for May 20 in Seattle District Court, Judge Elena Rivera presiding. SPD continues witness canvassing, with a hotline at 206-233-5000. Full probable cause docs expected public by May 17 .
