PENINSULA, Ohio (AP) — Authorities are asking experienced paddlers on the Cuyahoga River to be on the lookout for any out-of-the-ordinary items amid the search for a woman whose car was found in the Cuyahoga Valley National Park.

Thirty-year-old Hillary Sharma of Eastlake was last seen Tuesday and was reported missing by police on Thursday. The next day, her car was found in the parking lot at the main visitor center.

On Sunday, the search focused on a remote area of the 33,000-acre park along the river north of the village of Boston where some of her personal items were found.

Authorities have used search dogs, horse patrols, boats and a helicopter to look for her. The search will resume Monday.
