FARGO, N.D. (AP) — North Dakota authorities have charged a Minnesota man with manslaughter in the death of a Twin Cities woman after human remains were found west of Fargo.

The Cass County Sheriff's Office cautions that it's not certain yet whether the remains found Friday are those of 45-year-old Michelle Newell, of Vadnais Heights, who had been missing since late August. But it says the suspect, 51-year-old Timothy Barr, of Lakeville, provided information that led deputies to the remains.

Barr was originally charged in Minnesota with second-degree murder, but prosecutors dropped the charges last month, saying they lacked jurisdiction because there was no evidence the alleged crime was committed in Minnesota.

Barr is now awaiting an extradition hearing.

Barr's attorney did not immediately respond to messages seeking comment on the charges.
