From the EPD Press Release:

Detectives with Everett Police’s Major Crimes Unit have arrested a man believed responsible for a Feb. 12 armed robbery on Casino Rd.

An 18-year-old Lynnwood man has been arrested in connection with the robbery that occurred just after 9 p.m. on Monday, Feb. 12 at an AM/PM (901 W.
Casino Rd). Two men entered the business with a black rifle and demanded money. Both men were wearing masks of political figures and had distinct
clothing.

Detectives believe that one of the men was Joshua O’Connor, who was arrested on Feb. 14 for Attempted Murder 1st Degree for
planning and taking substantial steps toward executing a school shooting/bombing at ACES High School. When detectives served a search warrant on
O’Connor’s property, the masks, a gun, and a journal were found linking him to the robbery. The journal indicated “a friend” helped him with the
robbery but did not identify that person. DNA from the masks were processed by the Washington State Patrol Crime Lab, which identified the second
suspect.

The 18-year-old Lynnwood man was arrested this morning at ACES High School where he is a student. He has been booked into the Snohomish County Jail
on probable cause for robbery charges.

At this point, it is not believed this man was involved with Joshua O’Connor‘s plans to shoot students at ACES High School. (See news release dated

Detectives continue investigating both cases.
