MILL SHOALS, Ill.—Authorities in two states are searching for a gunman who killed an eastern Illinois deputy early Wednesday and is suspected in a carjacking in neighboring Missouri a couple of hours later.
The Wayne County Sheriff’s Office said in a Facebook post that Deputy Sean Riley responded to a motorist assist call on Interstate 64 near Mill Shoals around 5 a.m. Wednesday. A second officer who arrived at the scene found Riley dead. The deputy’s squad car was later found abandoned on I-64.
