Police in Kirkland are searching for two suspects after a man was fatally shot in Houghton Beach Park around 8 p.m. Wednesday. 

Kirkland police said Thursday on Twitter that investigators have determined the suspects appeared to know the victim, who was later identified by the King County Medical Examiner’s Office as 18-year-old Cyrus Mason.

The park, at 5811 Lake Washington Blvd. N.E., was temporarily closed for the investigation, but police reopened it Thursday afternoon.

According to police, there were several people in the park at the time, and witnesses reported hearing gunshots and seeing two males running from the park.

Police said they are working with witnesses and will release descriptions of the suspects when available. No arrests had been made as of Friday afternoon.

Q13 reported the investigation was focused on the park’s pier, where teens had reportedly been gathering without social distancing over the summer.
