Anyone in the area of east or west U.S. 35 around 2:30 p.m. Sunday who heard gunshots or saw anything suspicious is urged to call Riverside police at 937-233-1801 or police dispatch at 937-233-2080.
Sunday’s shooting was the second within a week that involved a fatality on an area highway.
Moraine police early Wednesday shot and killed a man on Interstate 75 who had been involved in a two-vehicle crash before he reportedly pointed a gun at Moraine officers.
Police said Elijah Isham, 27, ignored 41 commands to drop a gun before officers fired nine shots. Police later determined the . 44-caliber revolver was not loaded, but one of the officers saw him cocking the gun before they fired, Moraine Police Chief Craig Richardson said.
The officers involved, Sgt. Ken Lloyd and officer Jerome Klemmensen, are on paid administrative leave. The Ohio State Highway Patrol is investigating the crash and the Tactical Crime Suppression Unit — a collaboration of the cities of Centerville, Germantown, Kettering, Miamisburg, Moraine, Oakwood, Springboro and West Carrollton — is handling the criminal investigation. Moraine police is conducting an internal investigation.
