HARTFORD CITY, Ind. -- A man who police labeled a person of interest in the death of a Blackford County man was arrested Monday night in Madison County, authorities said.

Todd Walker, 34, was taken into custody and then transferred to the Blackford County jail, where he was being held on a charge of criminal confinement, according to police.

The Blackford County Sheriff's Department didn't say why Walker was being held on that charge, but it previously had said it wanted to question him about the death of Dustin Reid, whose body was found Sunday in a ditch near a rural road in Blackford County.

Police haven't said how Reid died.

Authorities said they are trying to find Walker's 1985 Ford F150 pickup truck, which has license plate number 881475L.

Walker was arrested after Blackford County authorities told the Madison County Sheriff's Department where Walker might be found, police said. Further details about the arrest weren't available.

Walker was being held Tuesday with bond set at $100,000.

Police said anyone with information about Reid's death should call the Blackford County Sheriff's Department at 765-348-0930.
