Many women in the metro are taking steps to make sure they're prepared for an attacker.
A self defense class held in honor of Andrea Kruger aimed to keep women safe.
Kruger, a mother, of three, was left shot and killed on a West Omaha road in August.
She is just one of several victims believed to be killed by Nikko Jenkins with the help of his family members.
Saturday was Lori Roberts' birthday, a sister-in-law of the Andrea Kruger.
She says after what's happened to Kruger and the other victims, the families will never be the same.
The gift that she wanted for her birthday this year was to know women got the chance to learn to defend themselves.
Dozens of women filled a gym at Lifetime Fitness in Omaha, hoping to feel safe again.
It was a self-defense benefit organized by Roberts.
"If we are prepared, then I think that we're able to walk strong in our community," she says.
With the help of Lifetime Fitness, Roberts was able to bring in self-defense experts.
Women learned how to protect themselves against moves like pushing, holding, and punching.
Now, they even know how to take down an attacker if they need to.
For Marley Macek and Emily Dahlgren, they hope they never have to use the skills, but want to be prepared.
"You never know what would happen. It's good to know a backup plan if something does happen," says Macek.
Building so much confidence for so many women is something Roberts knows would make Kruger proud.
"I know right now, Andrea is smiling down on us. This is what she would want. She was definitely a fighter, and a strong-willed woman," says Roberts.
All of the money raised at Saturday's benefit goes to the Kruger family.
Lifetime Fitness says it plans to start a continual self-defense class for women.
