ARLINGTON — A Marysville man should probably count himself out of the running for employee of the month at Walmart after being arrested for allegedly planting two bomb threats in the men’s bathroom.

He may have a shot at another award, though.

Turns out he reported finding his own notes to his bosses. The supervisors ended up calling police. The store was cleared out and bomb-sniffing dogs were brought in.

It also turns out that the handwriting on a statement he wrote for police matches the handwriting on the threats.

The man, 23, was arrested Tuesday. A judge on Wednesday found probable cause to hold him for investigation of threats to bomb. He was ordered held on $50,000 bail.

Arlington police say the man confessed to leaving the notes — one last week and a second one on Tuesday. He admitted that he was trying to harass a manager at the Arlington store, a man named Justin, according to a police affidavit filed Wednesday.

Police were first summoned to the Arlington Walmart just before 6 a.m. Aug. 25. They spoke with employees who had fled the store and were waiting in the parking lot.

The Marysville man told police he went to pick up some signs in the bathrooms after having mopped the floors there a few hours earlier.

The man told police he noticed a piece of paper on the counter. He read the note and reported the threat to a supervisor.

The Washington State Patrol bomb squad came to the store. Three bomb-sniffing dogs checked the building and vehicles in the parking lot. No bombs were discovered.

Then on Tuesday, Arlington police received another call about a second bomb threat at the store. A manager told officers that the same employee discovered another note in a restroom.

Police spoke with the Marysville man. He said he didn’t know who left the note, but he suspected a customer.

That’s when he wrote out a statement for police about his account of the incident.

Police noticed that his handwriting appeared to match that found on the note.

Officers reviewed video footage of employees going into the bathroom. The Marysville man was the last employee to enter and leave the restroom before the note was found.

Officers spoke with a second employee who had gone into the bathroom six minutes earlier. He didn’t report seeing a note.

Police chatted again with the Marysville man. He denied leaving the note.

Officers weren’t convinced. They arrested the man. That’s when he confessed, saying he was “Trying to (expletive) with Justin.”
