Oregon State Police are investigating a single car rollover crash that injured two; one seriously, Tuesday afternoon. 

Lt. Gregg Hastings reports Hazel Whapat, 57, of Warm Springs was driving eastbound on Highway 26 when she lost control of her car during a sweeping left curve, eight miles west of Madras. 

The car rolled at least once before landing on its wheels off the highway. 

Wahpat and her passenger, Leon Chase, 41, also of Warm Springs, were both injured and taken to St. Charles – Madras; but Whapat's injuries were deemed "serious" and made it necessary to transfer her by air ambulance to St. Charles Bend.

The crash occurred in one of the locations announced last week where OSP received an ODOT grant to provide overtime enforcement hours to prevent roadway departures.
