ST. PAUL - Minnesota prosecutors say blood on a pillow found during a search last weekend matches the DNA of 30 year old Kira Trevino.

The central Wisconsin native disappeared last month and her husband is charged with second-degree murder. Trevino is presumed to be dead. The pillow was found by a volunteer searcher near Keller Lake, along with a pillow case, sports bra, shirt and sponge.

The new evidence has been added to the criminal complaint filed against Jeffery Trevino. The search focused on that lake because one witness told police she was driving nearby February 22 - the day after Kira Trevino disappeared - and saw two men struggling with something which appeared to be about the size of a person.
