Helen Ainson was vandalized after its property manager discovered black spray paint on the rear of the building last week.

The vandalism was reported Feb. 20 at 9:44 a.m. after a property manager noticed a design of heads with several sets of eyes spray painted in black at the rear of the building, police said.

The property manager believed the vandalism happened overnight because there wasn't any graffiti on the building before 7 p.m. on Feb. 19, police said. No evidence of gang symbols, or "tags," were discovered and the damage estimate was unknown, police said.
