FAIRFIELD, OH (FOX19) - Three years ago this week, the remains of Katelyn Markham were found in rural Indiana.
As the days turn into weeks, the weeks into months and the months into years, Katelyn's father, Dave Markham is still hopeful.
"Yes. I'm confident we're going to get an answer," Dave Markham told FOX19 NOW.
This week marks three years since her remains were found by people searching for scrap metal along a creek in Cedar Grove, Ind.
She was 21-years old at the time of her disappearance.
"She was three weeks away from graduating with a bachelor's degree. She should have had it. She should be a graduate," Markham said.
Katelyn Markham was last seen in August 2011.
"My fiance is missing. I can't find her anywhere," said her fiance John Carter in a call made to 911 dispatchers.
Carter was the last known person to see Markham alive. FOX19 NOW contacted him by phone on Tuesday.
He declined a request for an interview.
After Markham's remains were found and identified, authorities ruled her death a homicide.
"I don't understand how somebody can carry this around in their hearts," Markham said.
Police in Fairfield and Indiana have worked on the case.
The Markham family has also enlisted the help of private investigators, and asked the Butler County Sheriff's Office to take a fresh look at the case.
Sheriff Richard Jones agreed to do so in December.
"There's been a lot of people vested in time and energy and money into this," Markham told FOX19 NOW.
Dave Markham says there is a $100,000 reward on the table for an arrest and conviction that'll hopefully entice someone to come forward with information about the investigation.
But, so far, there's no new break in the case.
"I'm confident that her case will be solved," he said.
