There aren't enough mental health counselors to respond to 911 calls. One county sheriff has a virtual solution.

Officer Dave Stiak didn't know what to expect when he got the call that someone was hanging over the railing of a bridge in Lemont, Illinois, a Chicago suburb. 

Stiak, a police officer for the Cook County Sheriff's Office, was on patrol with his partner in February when the calls started to come in. 

"He was standing outside of the safety railing, people were calling out to him," Stiak said. "He wasn't responding. He was looking off into the sunset. They said the guy looks like he's going to jump."
