Two years after a Winter Garden gym instructor was gunned down by a masked man during a CrossFit class, Richard Millsap's killer remains on the loose.

Millsap inspired many people to pursue a healthy and happy lifestyle through competitive fitness. Investigators continue to chase down leads, but Millsap's wife and child have learned to go forward in life without him.

"We had just celebrated our two-year anniversary," Karen Millsap said Wednesday, reliving the day her world came crashing down after she got a call that her husband was shot and killed.

Karen Millsap became a widow with a 2-year-old son to take care of on a single income. She struggled to keep going through her grief.

"Grief affects your mental state of being," Karen Millsap said. "And if you're not able to focus — if you're not able to be productive — then ultimately your work is going to suffer."

Karen Millsap lost her job about a year after her husband was killed. Instead of steeping lower into depression, she turned her pain into a purpose.

Now, she is launching a for-profit organization called Widows at Work, a service companies can hire to help their employees cope with the loss of a spouse.

"People will say, 'How are you doing?' I felt like the biggest liar, because I would say I'm OK, and it wasn't true," Millsap admitted. "Instead of asking that question, switch it to, 'How can I help you?' or 'What do you need?'"

The mentors at Widows at Work are also widows who help others going through similar situations. Millsap said the program would provide weekly guidance and coaching for both the employee and supervisor, so the transition back to a full-time work schedule can be managed with compassion.

"Richard would be proud," she said. "This has not defeated our family, and we won't let it defeat us. If anything, it's just going to let his legacy live on."
