WISHEK, N.D. (AP) — Prosecutors say they will not seek charges against officers in the case of man who died in police custody in south central North Dakota.

Forty-year-old Daniel Seminole was arrested in December near Wishek by a McIntosh County sheriff’s deputy and a Wishek police officer on suspicion of trespassing and providing false information to law enforcement. At one point Seminole allegedly attacked one of the officers and was subdued after a struggle. Seminole later stopped breathing while in the back of the squad car.

Medical examiners say Seminole died from a combination of methamphetamine use and heart disease.

McIntosh County prosecutor Mary DePuydt says she did not find probable cause for criminal charges against the officers. A spokeswoman for the North Dakota attorney general’s office says the investigation is officially closed.
