MARYSVILLE — At approximately 11:34 p.m. on Aug. 15, Marysville Police were called to investigate a possible vandalism in progress at Grove Elementary, in the 6400 block of Grove Street, after a neighbor reported hearing several subjects on school property and what sounded like spray paint being applied.

Officers arrived and observed three teenage boys on the ground and one on the roof of the school. The officers also observed a large quantity of recently painted graffiti damage to the school building. Also located at the scene was a backpack belonging to one of the boys that contained spray paint cans of the same colors as the graffiti on the school.

Three of the boys — two aged 14 and one aged 15 — were from Marysville, while the other boy, aged 14, was from Lake Stevens. All four were detained while police completed their investigation.

Marysville School District Security was called to the scene by police. School security personnel verified that the graffiti had not been there earlier in the evening.

Subsequent reports showed additional nearby locations of graffiti damage, including the Marysville Public Library.

All four boys were booked into the Denny Juvenile Justice Center on suspicion of malicious mischief in the first degree.
