A man entered Island Books at 6:45 p.m. on July 21, displayed a handgun tucked into his waistband and requested all of the money in the cash register.

A store employee complied with the demand, and the suspect fled the store with an undisclosed amount of money, according to Mercer Island Police Department Commander Jeff Magnan.

“Thankfully no one was harmed and everyone is OK,” store owner Laurie Raisys wrote on the Island Books Facebook page. “Our staff is like family to us and we value their safety and well being over any money or material things that may have been taken.”

Mercer Island patrol officers responded to the store, setting up containment and attempting a K9 track with the help of Bellevue Police Department, but did not catch the suspect.

Island Books remained open for business over the weekend.

Latent fingerprint evidence was recovered from the scene, and detectives are following up on some potential leads. The investigation is ongoing and updates will be posted when available.
