The face of Nancy Lyons, 46, is still clear on a utility pole poster photo, having withstood unyielding elements over the years, 6News' Derrik Thomas reported.

Lyons' car was found abandoned on a rural county road in northwestern Rush County on June 17, 2002. Her body was found in October 2002 50 miles away.

A Wal-Mart surveillance video was the last time she was seen alive.

Family members are frustrated by the length of the investigation and lack of answers, but there could be a break in the case.

"I believe they have what they need and the next step is going to the prosecutor's office, which will be soon," said Deborah Mitchell, Lyons' sister. "I believe they have a case."

The family might be overly optimistic. Indiana State Police told 6News that it will submit a summer of the case to the prosecutor by July 31, but there is not a person of interest or suspects in the case.

"Our investigators remain on the case. The case is open. The case has also been referred to the FBI for their assistance," said ISP Sgt. John Bowling.

While the news is not good for the Lyons family, they vowed not to give up.

"I believe she's at peace. I believe that," Mitchell said. "But we can't rest until justice is served."

Family members said they would like closure for Lyons' 80-year-old father and 77-year-old mother, along with the five surviving siblings.
