Breaking: Suspected cop killer caught in Tennessee after dayslong manhunt

Authorities captured the man suspected of killing a Dickson County, Tennessee, police sergeant Friday morning after a manhunt that stretched nearly three days, The Tennessean reported.

The suspect, 31-year-old Steven Wiggins, was arrested by a Tennessee Highway Patrol trooper in Hickman County. He was reportedly found laying on the side of the road.

The Tennessee Bureau of Investigation posted pictures on its Twitter account of Wiggins being put into a law enforcement vehicle.

What happened?

Wiggins is charged with first degree murder for allegedly shooting and killing Dickson County Sheriff's Office Sgt. Daniel Baker, who was found dead in his patrol car Wednesday morning. Baker had responded to a call about a suspicious vehicle before he was killed.

Wiggins was wanted on multiple warrants at the time. The day before Baker's death, Wiggins allegedly attacked Erika Castro-Miles, an acquaintance who has also been charged in Baker's murder after admitting she was with Wiggins at the time.

According to court documents, Castro-Miles was charged with first-degree murder because she "was seated in the vehicle with Steven Wiggins when he did shoot and kill Sgt. Daniel Baker with premeditation."

The state will reportedly seek the death penalty for both Wiggins and Castro-Miles.

Police don't have a motive for the killing yet.
