June 17 marked the anniversary of the disappearance of Lyons, 46, whose abandoned vehicle was found on a county road. She was last seen in a Walmart surveillance video.

Lyons' body was not discovered until October 2002, found in soybean field in Columbus.

"I know she would want us to continue to work and those that did this to her be held accountable," said Bev Tallent, one of Lyons' sisters.

The entire family gathered Wednesday for a memorial ceremony at the same intersection where Lyons' vehicle was found.

"We want to see justice. We're here to get the attention of someone who knows something," said Krista Crabtree, Lyons' niece.

Indiana State Police investigators conducted an exhaustive probe, but came up empty, 6News' Derrik Thomas reported.

"This is still an open case. We will welcome the opportunity for any new … leads we can look at, and if we have any of those, we encourage people to call the Indiana State Police with that information," said ISP 1st Sgt. Dave Bursten.

Family members wore "Remember Nancy" ribbons on their shirts. While they remember her life vividly, family members hope the public doesn't forget her.
