A man is in custody and a woman has been found dead after a lengthy standoff in Red Wing, authorities said.

Authorities are investigating a fatal three-vehicle crash that occurred early Saturday morning on Highway 52 in Pine Island Township.

Just before 1 p.m., an officer reported a male driver crashed into a power pole near the marina and was walking away from the vehicle. A short time later, the man was reported to be suicidal and was "attacking" an officer on scene in the parking lot.
