Divers continue to search the water and volunteers with dogs continue to search the banks along the Wabash River in Lafayette.
The team of about 30 is searching for the remains of Steven L. Smith.
The 52 year old has been missing since December 6.
Currently in custody is a man who police believe knows how Smith died.
Convicted child molester Wesley Kelly, 28, has not been charged with the homicide.
Kelly is being held on an unrelated burglary charge and for failing to register his address with Indiana's Sex Offender Database.
"I didn't even know Stacy Peterson when she went missing in Bolingbrook and I volunteered. I've been doing that for 13 months," Noun tells FOX 59.
Investigators believe Steven Smith and Wesley Kelly got into an argument the night of Smith's death.
