The father of a Maryland teen who survived a car accident and then her rescue helicopter’s crash says his daughter can’t speak but squeezes his hand.

Scott Wells told reporters at a trauma unit Monday that his 18-year-old daughter was trapped in the woods for an extended period of time after the weekend crash. Four other people were killed.

He didn’t talk much about her injuries, but says he and his wife, Lynn, are thankful their daughter is alive. He says he and his wife just want to be Jordan’s parents right now because that’s what she needs.

Authorities are combing through the wreckage of the aircraft and trying to determine what went wrong. The pilot radioed just before the crash that he was having trouble assessing his surroundings.
