"Not a super big rush," Crawford said.
I asked if he could pull under the bridge just in case the individual decided to jump," Sheriff told KTVT. "And that's what happened. As soon as the truck driver was able to get under the bridge, the subject jumped off the bridge. Fortunately, the driver was there and (the teen) landed on top of the trailer."
Crawford said he normally does not like to see a police officer approach his cab window, but Wednesday was different.
"He was coming to me," Crawford told WFAA. "He said, 'This guy's going to jump.'"
The boy jumped on top of the rig but he was safe, the television station reported.
"By me being there, I gave him a different option," Crawford told WFAA.
Crawford told KTVT he has lost family members to suicide.
“I’ve had it happen in my family -- loss due to suicide and it’s not a good thing,” Crawford told the television station. “(I) always ask what could I have done. Well, today, I did something. Maybe he can get some help. Maybe he can’t. But today it didn’t happen.”
