A suspect in an Iowa killing was arrested Friday outside a marijuana dispensary in South Dakota, authorities said.

Nathanial Byron Kessel, 41, of Rock Rapids, Iowa, is now awaiting extradition. He was taken into custody on the first-degree murder warrant after the Flandreau Santee Sioux Tribe police chief noticed a vehicle that Iowa officials were seeking at the Royal River Casino and Hotel in South Dakota, KDLT-TV reports.

The police chief then alerted other agencies and Kessel was apprehended outside the Native Nations Cannabis Dispensary, a spokesman for the tribe said.

Kessel also is accused in the arrest warrant of being a felon in possession of a firearm, the Iowa Division of Criminal Investigation said in a news release.
