Authorities say suspects have confessed to vandalizing an area of Stumpy Basin in Cuyahoga Valley National Park.

Park spokesperson Pam Barnes said she wasn't sure how many people were involved or their ages, but she said there were multiple people involved.

Barnes said park rangers, who identified the suspects, are still working on their investigation and will release additional information, including if the people involved will face any charges.

Vandals spray-painted graffiti and carved initials into a wooden boardwalk along the Towpath Trail about a mile north of Peninsula. The vandalism was found Tuesday, so authorities aren't sure when it occurred.

They wrote "The Gang Waz Here" in yellow paint. There also is a blue heart with the words "Josh + Aliesha."

In a Facebook post on the national park's page, officials thanked everyone who provided tips and shared the post.

"It takes a community to care for your national park," the post said.
