WASHINGTON COUNTY, Oklahoma - The Oklahoma Highway Patrol is investigating a rollover crash in which two Bartlesville residents were injured Monday evening on Highway 75.

Troopers said the 9:54 p.m. crash happened about 3 miles south of Bartlesville.

The OHP report states two SUVs were northbound on Highway 75, when a 2007 Toyota 4 Runner, driven by Justin Nauer of Bartlesville, made what troopers called an unsafe lane change, driving into the path of a 2008 Lexus SUV.  

They say that caused the Lexus driver to go off the road, rolling over several times.  The driver, identified as 26-year-old Robert Lay and a passenger, 26-year-old Elizabeth Lay were flown by helicopter to a Tulsa hospital.  

The OHP says Robert Lay, who was found 60 feet from his SUV, is in critical condition with head and internal injuries.  Elizabeth Lay was found underneath the SUV, according to the OHP.

They say, neither was wearing a seat belt at the time of the crash.

Troopers said Justin Nauer was not injured.
