(CNN) Workers removing shelves and coolers from a former No Frills Supermarket in Council Bluffs, Iowa, in January discovered a body behind one of them.

The remains were recently identified as those of Larry Ely Murillo-Moncada, a former employee who had been reported missing November 28, 2009.

Investigators used his parents' DNA to confirm the identity, and the clothes matched the description of his attire at the time he was reported missing, according to Council Bluffs Police Capt. Todd Weddum.

Murillo-Moncada's parents reported their son missing after he became upset and ran out of their home. They told police at the time that he was acting irrationally, possibly because of medication he was taking, Weddum said.
