A woman had allegedly been floating on an air mattress for two days on Lake Texoma in Oklahoma when train crew members and authorities came to her rescue on Thursday.

The woman, who identified herself only as “Connie,” said that she and a man had attempted to use the air mattress as a raft to retrieve a boat, which was out on the lake.

As BNSF railroad crewmembers Conductor Cristhian Sosa and train engineer Justin Luster were traveling from Irving, Texas, to Madill, Oklahoma on Thursday, they saw the woman flailing her arms and screaming for help.

“She was literally laying on the ground waving one arm, basically her left arm, the one that her arm wasn’t stuck with her jacket and she was asking for help so we instantly knew she was hurt and she needed help,” Sosa said.

Lena Kent, the general director of public affairs BSNF Railway, said the woman had cuts on her hands, which were bleeding and she was exhibiting symptoms of hypothermia.

The woman told the Sosa and Luster that she had been floating on the lake for two days before she drifted to the shore. Believing that she may have been delirious, the two called 911 and met with a highway patrolman at the next crossing, according to KXII.

Bryan County EMS took the woman to a nearby hospital where she has been treated and expected to make a full recovery.

The man who the woman said had been with her allegedly found his way back to shore, however, the Ohio Highway Patrol suggested that there could be more to the story and they are working to find answers.
