EDINA, Minn. — Authorities say the man wanted for double murder in Illinois shot himself during a standoff with police in the Twin Cities area.

Police in the Minneapolis suburb of Edina responded about 8 p.m. Friday to a tip regarding a wanted criminal. They found an armed man sitting in a white Nissan Versa hatchback. Police attempted to negotiate with the man, later identified as Anatoliy Ermak, 64, before he shot himself.

He was transported to an area hospital in critical condition.

Ermak is suspected in the killings of his ex-wife, 55-year-old Nataliya Ermak, and her husband, 69-year-old Roman Frid.

They were gunned down last Sunday night in Buffalo Grove, a northwestern suburb of Chicago.
