Fort Lauderdale, Florida -- Authorities have released the 911 calls of bystanders who reported seeing a woman dangling from a Fort Lauderdale bridge after she participated in a cancer walk on Saturday, Oct. 12.
The video above shows cell phone footage of Wanda McGowan grasping on for dear life as she waited for firefighters to rescue her.
Authorities say she walked across the railroad bridge -- even though there are numerous "No Trespassing" signs posted in the area -- just as it started to open.

McGowan's friend told authorities she's legally blind which possibly explains how she ended up on the bridge at the exact moment.
