MISSISSIPPI (CNN) — Mississippi authorities are questioning a man suspected of impersonating a police officer to determine whether he is involved in the killings of two motorists on highways in the state, a sheriff's investigator said Thursday.
The man was picked up after stopping two drivers, Humphreys County Sheriff Investigator Sam Dobbins told CNN. He was driving a blue Mercury Marquis that used to be a police car and still had flashing blue lights on top, Dobbins said.
Investigators have raised the possibility that someone posing as a police officer is to blame for the shootings, which happened 55 miles apart. Ballistics tests have linked the killings, a source who has been briefed on the investigation said Thursday.
