BAKER CITY — Oregon state troopers say at least four vehicles hit a cow that wandered onto Interstate 84 Friday night, killing it. Then a Lincoln Continental struck the carcass and rolled, killing a passenger.

Troopers said Saturday they’re investigating how the cow got onto the highway.

They identified the victim as 62-year-old Gary Glascock, of Vale.

The driver was 57-year-old Donald Hodge, also of Vail. Troopers say he was treated for injuries that weren’t life-threatening.
