Sergeant Ira Parker, 41, was shot and killed on July 9, 1987, in Inkster, Michigan, while responding to a call at a motel on Michigan Avenue. A 15-year veteran of the Inkster Police Department and a United States Air Force Vietnam veteran, Parker arrived to assist officers who were serving a warrant related to a bad check for a 68-year-old woman. When Parker entered the room the suspects opened fire; Parker and two other officers, Daniel Dubiel and Clay Hoover, were struck by multiple bullets and killed instantly. Ballistics testing showed the officers were shot with the revolvers they had carried into the room as well as weapons owned by the suspects.

The shooting was followed by a ten-hour standoff. The suspects — identified as 70-year-old Alberta Easter and her three sons Roy Lemons Jr., William M. Lemons, and George L. Lemons — fired hundreds of rounds, wore gas masks during police use of tear gas, and initially told negotiators the officers were hostages. After surrendering, all four were charged with first-degree murder, pleaded not guilty, and were later convicted and given three life terms each. Alberta Easter died in prison on June 12, 2011; one son died in prison in 1996. Sergeant Parker was survived by his wife and four children.

Are there details about the motel, the warrant that brought the officers there, or the early investigation that anyone can add?
