PORT ORCHARD — A dispute at Waterfront Park between two men over an unrestrained dog on the afternoon of Jan. 8 escalated into a physical confrontation in which one man reportedly was punched and the other stabbed with a knife.

A certificate of probable cause issued by Port Orchard Police in a Kitsap County Superior Court hearing Thursday reported that the stabbing victim, 33-year-old Ivan Carlson, told officers that Dylan G. Sperstad, 27, listed as a transient, approached him in the park wearing all black clothes.

Sperstad, he said, yelled at him for allowing his dog to wander unrestrained in the park after Carlson’s canine to walk up to him with no leash. Sperstad told officers that he yelled at the dog to get away and told Carlson he was violating the city’s leash law. It was at that point that Carlson got angry and hit him with a closed fist, sending him to the ground, he said.

Sperstad then told police officers that Carlson jumped on top of him and held him down, saying, “I’m going to kill you.” He then said he reached for a knife in his waistband, removed it and stabbed Carlson stabbed him once in the chest. Sperstad said after yelling for Carlson to stop, he tossed his knife into the grass area away from the confrontation.

An officer who examined Sperstad for injuries said she didn’t see any that would suggest he had been assaulted by Carlson. Sperstad was arrested by the officer for first-degree assault. Carlson was taken by medics to Tacoma General Hospital, where he was admitted with a punctured lung. The police report stated that the stabbing victim will most likely remain hospitalized for a few days.

Port Orchard Police Chief Matt Brown said the incident was a private dispute between the two men and wasn’t as a result of a random attack.

Bail for Sperstad was placed at $50,000.
