MAPLEWOOD (AP) - Authorities have found nothing in their first open-water search of a Twin Cities lake for the body of a missing woman.

The Ramsey County Sheriff Office's water patrol had a single boat on Keller Lake Tuesday in the search for 30-year-old Kira Trevino of St. Paul.

Sheriff's spokesman Randy Gustafson says it was the first time authorities have been on the lake since the ice thawed. He says crews used sonar but were not diving.

Trevino, a central Wisconsin native who was last seen alive Feb. 21, is presumed dead. Her husband, Jeffery Trevino, is charged with second-degree murder in her disappearance.

Civilian searches turned up evidence near the Maplewood lake including a plastic bag. Inside was a pillow that had blood matching Kira Trevino's DNA.
