20-year-old Mollie Tibbets was found dead near her home in Brooklyn, Iowa.
But, local running enthusiasts we spoke with say the news won't keep them from the sport they love.
Instead, they will stay more alert.
The running director at Elevate Fitness points to multiple safety tips.
Be aware of your surroundings at all times.
That means leaving one of your ear buds out.
It's best to run in groups or with a buddy, especially at night.
Also, jog in areas with surveillance cameras.
"One of biggest mistakes people make is they don't play dirty enough," said Kevin Collins, the Elevate Fitness running director. "If you have an attacker, you really have to fight for your life, and you have to think about unfortunately, the best defense is a good offense."
Collins also says it would also help to learn self-defense techniques to protect yourself in all situations.
