HENDERSON, Neb. (AP) — County officials say a McCook man has died of an apparent heart attack he sustained while driving along Interstate 80, causing a two-vehicle crash.

Hamilton County Attorney Michael Powell says the collision occurred around 5:10 p.m. Monday about seven miles east of Aurora. He says 70-year-old Victor Schwartz was driving eastbound when he began swerving onto the shoulder and back onto the road, and then jerked sideways.

Powell says another eastbound vehicle then struck Schwartz’s car just behind the driver’s door. The condition of the driver wasn’t immediately available.

Schwartz was pronounced dead on arrival at Henderson Health Care Services. Powell says both the death and crash appear to have been caused by a medical episode, likely a heart attack.
