Telemarketers can be annoying for many, but for one Oregon woman, it saved her from a vicious attack.

Trace Gallagher reported on "The Real Story" about a Las Vegas telemarketer with Americare Health and Nutrition who was making a sales call and ended up hearing a woman being attacked 900 miles away from the call center.

Gallagher said that the woman didn't know the phone was ringing when the call was accidentally picked up from her pocket. The telemarketer alerted Tina Garcia, a supervisor at the call center, about the victim's screams for help.

"It was very very frightening," Garcia said. "That young lady was helpless. You could actually hear the blows as if he was hitting a punching bag and she was terrified."

Garcia called the Lynn County Sheriff and gave officials the victim's phone number who tracked it to a home.

Gallagher reported that when officials arrived to the home, they found the suspect, Walter Ruck, behind the victim with his hands around her neck.

Ruck was arrested and is facing charges for assault and strangulation.
