Human remains that were found in Lincoln County on Nov. 15 are those of Justin Diemel, 24, the younger of two brothers who disappeared in July in western Missouri, the Caldwell County sheriff’s office said Friday.

Sheriff Jerry Galloway said the remains of the other Diemel brother, Nicholas, 34, were found on a farm in Caldwell County, Mo.

He said the identities of both men were confirmed by dental records.

The Diemel brothers owned a livestock operation in Shawano County, Wisc. and did business in a wide area, including the farm of Gaylord Joseph Nelson of Braymer, Mo., some 600 miles away, east of Kansas City.

The brothers went missing July 21, after they traveled from Wisconsin to Missouri, apparently to try to settle a cattle deal with Nelson.

Justin Diemel’s remains were found in a tub stored in a livestock trailer that was purchased in Missouri and brought to a livestock operation between Hershey and Dickens.

In August, Galloway announced that that human remains were found on Nelson’s farm, but the identity of those remains was not announced. It was not immediately clear Friday afternoon if those remains were Nicholas Diemel’s or those of someone else.

Gaylord Nelson, 25, is in custody in the Caldwell County Detention Center in Kingston, Mo. He is held without bond.

Nelson is now charged with two counts of first-degree murder; two counts of abandonment of a corpse; two counts of tampering with physical evidence; two counts of armed criminal action; as well as tampering with a motor vehicle and unlawful possession of a firearm.

The Caldwell County Sheriff’s Department and the Missouri State Highway Patrol continue to investigate the case, Galloway said Friday.

Galloway said the charges are accusations and not evidence of guilt. He said the supporting evidence will be presented before a court, whose duty is to determine guilt or innocence.
