A West Seattle boat owner paddled out to confront a trespasser aboard his own vessel in Fauntleroy Cove Tuesday afternoon, only to have the man allegedly brandish a knife at him before fleeing across open water in a stolen dinghy — kicking off a pursuit that stretched roughly six to seven nautical miles north to Elliott Bay Marina, where the suspect vanished into the woods and remains at large.

According to KOMO News, the incident began around 2 p.m. Tuesday when the boat owner interrupted what police describe as a theft in progress on his boat in Fauntleroy Cove. Police say the suspect brandished a knife at the boater before fleeing in a dinghy, prompting the victim to give chase. A separate account posted to a West Seattle Blog community forum describes the boat owner paddling out after a neighbor reported a trespasser, and confronting a mid-40s man with a salt-and-pepper beard wearing a yellow-and-black life jacket inside the cabin, who then fled in a black Highfield inflatable dinghy loaded with suspected stolen gear.

Coast Guard Joins a Chase Across Open Water

The pursuit didn't stay confined to Fauntleroy Cove. The U.S. Coast Guard intervened during the chase Tuesday, attempting to corral the suspect into Elliott Bay Marina, according to police cited by KOMO. During that encounter, police say the suspect also brandished a knife at Coast Guard personnel. The stretch of water covered — from Fauntleroy Cove in West Seattle north to Elliott Bay Marina in Magnolia — spans approximately six to seven nautical miles across central Puget Sound, a distance that underscores just how far the confrontation traveled before it reached shore.

Central Puget Sound waters around Elliott Bay fall under overlapping jurisdiction, with the Port of Seattle Police Department's Marine Patrol and Dive teams maintaining coverage from Alki Point Lighthouse to West Point Lighthouse in Discovery Park under mutual-aid agreements with Seattle police, according to the Port of Seattle. That layered coverage helps explain how Coast Guard, Seattle police, and port authorities were all positioned to respond as the chase crossed from West Seattle waters into Magnolia's shoreline.

Suspect Abandons Dinghy, Disappears Into the Woods

According to police, the suspect eventually beached the dinghy at Elliott Bay Marina and fled on foot into the woods. Elliott Bay Marina is the largest privately owned marina on the West Coast, with more than 1,200 in-water slips and 10 miles of dock space at the base of Magnolia, per the marina's own description — a sprawling stretch of shoreline that could have offered the suspect plenty of cover once he ditched the boat.

Seattle police officers responded to search for the suspect and brought in a K-9 team to track him through the wooded terrain near the marina. Seattle police units routinely coordinate with harbor patrol during these kinds of water-to-land tracking operations, deploying search dogs when suspects abandon boats for coastal woods, according to the Seattle Police Department. Despite that effort, the suspect had not been located as of the latest update, and his identity and current whereabouts remain unknown.

What Charges Could Follow

The suspect faces significant legal exposure on two fronts if identified and caught. Under state law, intentionally assaulting someone with a deadly weapon such as a knife constitutes Second-Degree Assault under RCW 9A.36.021, a Class B felony carrying up to 10 years in state prison and a $20,000 fine, according to legal resources cited in the dossier. Separately, forcibly assaulting or brandishing a deadly weapon at a Coast Guard member performing official duties is a federal felony under 18 U.S.C. § 111, punishable by up to 20 years in federal prison, per legal analysis from Eisner Gorin LLP.

A Busy Season on the Water

Tuesday's chase adds to a string of dramatic marine responses around Seattle's waterways this year. In June, a 66-year-old man died after being pulled from the water near the Fauntleroy ferry dock, prompting local warnings about water safety in the same cove. In August, Seattle Fire marine units rushed a rescue boat to Elliott Bay after someone fell from an Alaskan Way pier, and separately, a 30-foot powerboat caught fire at a Seattle marina, forcing crews to evacuate docks and push nearby vessels to safety. Police have not released further details on the Fauntleroy Cove suspect's identity, and the search continues.
