Trial has been delayed more than two months for a man accused of killing one man and critically injuring another on the Spirit Lake Reservation.

FARGO, N.D. (AP) — Trial has been delayed more than two months for a man accused of killing one man and critically injuring another on the Spirit Lake Reservation.

The attorney for Dallas Thundershield says he needs more time to prepare. Federal prosecutors didn't object to the request, and U.S. District Court Chief Judge Ralph Erickson moved the trial start from July 5 to Sept. 20.

Thundershield is accused of killing Richard Dumarce Sr. and injuring Elvis Demarce in an April 9 fight that began while the three were driving around with Thundershield's girlfriend.

Thundershield is accused of using his vehicle, his booted foot and a knife as weapons. He has pleaded not guilty to murder and assault charges, and remains in custody while awaiting trial.
