SEATTLE - Seattle police said they have the DNA of a person who fatally stabbed a 22-year-old man near Alki Beach on June 2.

Though police have the DNA, Assistant Chief of SPD's Investigations Bureau Deanna Nollette said it doesn’t match anyone in state or federal criminal databases. On Wednesday, the department released a plea for help drumming up tips.

In a more than two-minute YouTube video, Seattle police showed footage from the crime scene. They also showed forensics investigators at work, play body camera footage and end with Nollette’s request.

"This case will never go away," Nollette says in the video. "We have your DNA. It is in your best interest to contact us immediately."

Nollette said this is the first time the department has had their video production team create an video in the hopes of generating leads. She said it won’t be the last.

“It is a rather graphic video. It brings home the feeling and the violence of what happened that evening,” Nollette said.

Nollette said the stabbing victim, identified as Jonathan Pecina, and a friend were walking on the Alki Trail near Luna Park.

Police said witnesses later told them Pecina and his friend were acting aggressively, confrontational and belligerent toward others walking in the same area.

At about 10 p.m. Pecina and his friend encountered another man on the street. There was some type of fight and Pecina was stabbed in the neck.

On Wednesday, Nollette said their goal is to bring answers to the slain man’s family.

“He deserves justice and his family deserves closure,” she told KOMO.

Nollette said Pecina’s family has seen the video Seattle police created, which by Wednesday night had been viewed more than 9,000 times, and were “distressed” by the details inside it.

Nollette said investigators want to know what happened directly from the person who stabbed Pecina. Investigators said it’s unclear what led to the stabbing or if there was some element of self-defense.

“At some point this individual will be identified. We want them to have the opportunity come forward and tell us their story,” Nollette said.

Anyone with information is asked to call SPD's Homicide Unit office (206) 684-5550, or the department’s tip line (206) 233-5000.
