It's a crime that can rob you of your freedom, take your life, and sense of security.
Every year more than six million people are stalked in the U.S. January is National Stalking Awareness Month.
Tuesday night Saint Mary's College welcomed a well-known speaker that shared her personal story. Debbie Riddle spoke to a room full of students and showed a video that aired on Lifetime.
Ten years ago her younger sister, Peggy Klinke, was murdered by her ex-boyfriend.
It happened after she broke up with him and he stalked her for at a least year.
During that year he was obsessed with her and wouldn't leave her alone, despite a restraining order.
He even burned down part of her new boyfriend's house, sprayed nasty comments about Klinke on her mom's garage and forced her to leave the state to hideout while waiting for the trial.
But it was days before the trial that her ex-boyfriend found her. He shot Klinke and then himself in the head.
Now her older sister travels around the country sharing the story and hopes to bring awareness to this serious crime.
“I really think we need to raise awareness on both sides of the fence,” says Riddle. “The criminal justice system needs to treat these victims with respect and to hear about the definition of what is stalking.”
Stalking is a crime in all 50 states.
Riddle says a year after her sister died Congress recognized January as National Stalking Awareness Month. Plus now law enforcement agencies go through more training on the topic than before.
