Jordan Turpin details making 911 call moments after she escaped family's 'house of horrors'

Jordan Turpin placed the call shortly after making a decision that would change her family’s lives forever.

The 17-year-old said her hands were shaking uncontrollably as she made the brave decision to dial 911 in 2018. She said it was one of the few times she had been outside in that California neighborhood.

“I was actually on the road,” Turpin, now 21, said in an exclusive interview with ABC News’ Diane Sawyer, “because I didn’t even know about the sidewalks. You’re supposed to be on the sidewalk, but I’d never been out there.”

Watch the Diane Sawyer special event, "Escape From A House Of Horror," on Friday, Nov. 19 at 9 p.m. ET on ABC and stream on Hulu.
