MILLER, S.D. (AP) — Authorities say two men from eastern South Dakota died in separate rollover accidents in West River over the weekend.

The South Dakota Highway Patrol says 37-year-old Victor Grassrope of Huron ran a stop sign while he was driving near Miller on Saturday morning. It says Grassrope's vehicle then went off the road, collided with a tree and rolled on its roof.

The Highway Patrol says 53-year-old Lynn Weischedel of Onida may have over-corrected his vehicle after driving onto the shoulder of U.S. Highway 83 near Pierre on Sunday morning. It says Weischedel was ejected from the vehicle after it went into a ditch and rolled.

Officials say both men were pronounced dead at the scene, and neither was wearing a seatbelt.

Investigations into both fatal crashes are ongoing.
