Twin girls, 4, free themselves from car seats to survive crash that killed their dad

Twin 4-year-old girls managed to survive a car crash that killed their father by unlocking themselves from their car seats and climbing an embankment to get help, say Washington state officials.

The girls' dad Corey Simmons, 47, died at the scene after his car veered off a winding road on Friday evening and dropped off into a forest 200 feet away, reported KING-TV and CNN.

The father sustained fatal head injuries. He wasn't wearing a seatbelt, USA TODAY confirmed.

Police say the twins had non-life-threatening injuries, and were transported to a hospital after a woman who passed the crash in her car drove back to help and called 911.

Family members told KING 5 the two 4-year-old girls in the backseat of the vehicle were Simmons' twin daughters. The girls were able to free themselves from their car seats and climbed about 200 feet to the road for help after the crash.

Trooper Axtman said a Good Samaritan passed the girls on the side of the road and turned around to help. The driver called 911 and the girls were transported to the hospital with minor injuries.

Rebecah Crider is Esther Crider's daughter and Simmons' stepdaughter. She said her family searched for the Good Samaritan who helped her sisters after the crash.

"We are so incredibly thankful, and we are desperately looking for who she is," Rebecah Crider said. "We would love to personally meet her and thank her."

On Sunday, Seattle authorities made contact with the Good Samaritan. She did not want her name published.
