Casper, WY (AP) - Two young sisters are dead after their mother lost control of her sport utility vehicle in Fremont County.
The Casper Star-Tribune reports that 6-year-old Olivia Lewis and 3-year-old Emma Lewis were flown to a Salt Lake City hospital after Tuesday's crash but didn't survive.
The Wyoming Highway Patrol says mother Becca Lewis wasn't hurt. She lost control while driving on Highway 789 between Hudson and Lander, spinning into oncoming traffic. Sgt. Stephen Townsend says a truck then broadsided their SUV.
The father of the girls, Sean Lewis, is a professor at Wyoming Catholic College.
WCC president Kevin Roberts says the school is deeply saddened by the tragedy and that many friends and family have been touched by the girls, who leave behind another sister.
