KALISPELL, Mont. (AP) Flathead County sheriff's deputies say a man whose girlfriend was found shot to death has surrendered after a 31-hour standoff.

Authorities say 46-year-old Robert Kowalski was taken into custody at his Creston home on Monday.

Sheriff Mike Meehan says Kowalski's girlfriend, 45-year-old Lorraine Morrin, was found shot to death Sunday at her house near Columbia Falls.

She had six children ranging from 9 to 28 years old.

Meehan says Kowalskis roommate told a 9-1-1 dispatcher on Sunday that Kowalski said he had killed his girlfriend and was feeling suicidal.

Officers surrounded Kowalski's house at about 2 p.m. Sunday.

Deputies say he fired at least one shot into the air with a pistol.
