A sign on the Sandy Hook Memorial Playground at Penfield Beach that honors Jessica Rekos, one of the 20 first-graders killed in the mass shooting at Sandy Hook Elementary School in Newtown on Dec. 14, 2012, was vandalized sometime over the weekend.

The vandalism, which defaced the sign with a series of scratches, was reported to police at 11:29 a.m. Tuesday by a firefighter, police said.

The cost to replace the sign is about $350, police said.
