The shocking murder of Mollie Tibbetts is a grim reminder how vulnerable people, particularly women, can be when going out for a run alone. Fortunately, there is an arsenal of high-tech safety devices available to help keep joggers safe.
Inside Edition tested the LifeLine Response app, which uses GPS information to help emergency responders locate people who need them.
When correspondent Megan Alexander dropped her phone, the app alerted police and let her know they were on their way.
In Inside Edition's test, it took just two minutes for police to arrive.
Other gadgets include the Defense Alert Device, a personal safety device equipped with smart technology to alert family and friends if you need help, and the Tigerlady Self-Defense Claw, a lightweight claw that's easy to carry and hide while jogging but can cause some serious damage.
And when all else fails, fight back.
Tibbetts' accused killer allegedly stalked her and confronted her as she was running. The 20-year-old told the man that she would call police.
"Mollie said, 'You need to leave me alone. I'm going to call the police.' And she took off running," officials said at a press conference Tuesday.
But it wasn't enough. Tibbetts was found dead Tuesday morning.
“Our hearts are broken," Tibbetts' family said in a statement. “We thank all of those from around the world who have sent their thoughts and prayers for our girl. We know that many of you will join us as we continue to carry Mollie in our hearts forever."
