As CrimeOnline previously reported, Nick Diemel and his brother Justin were in Missouri related to their cattle business when they disappeared. The brothers flew from Wisconsin to Missouri on July 20 to visit several farms that raise calves, according to their family.

The brothers are co-owners of Diemel’s Livestock and made plans to see calves during the trip.

Nick’s wife, Lisa Diemel, knew something was wrong when they missed their 1:30 p.m. return flight the following day. Earlier this week, she filed a petition at the Shawano County Circuit Court asking the court to appoint her as special administrator for the estates of the brothers.

According to the Green Bay Gazette, Lisa wants to manage their business assets “until full probate administration can be commenced.”

Lisa said she was last in contact with her husband at 8:55 a.m. the following morning after they arrived in Missouri. The brothers were preparing to visit a farm to check on their calves.

The black 4-door Ford F-250 truck the pair rented for their stay was found abandoned Monday at a commuter lot in Holt, Missouri, with their carry-on luggage still inside.

“I honestly don’t know what’s happened to them, but something isn’t right,” Lisa Diemel, who shares four children with her husband, told NBC 26.

“We are in shock. I mean I can’t even believe that something like this can happen……They found the abandoned truck on the side of the road with their carry-ons and that was it.”

Searches were previously conducted in both Clinton and Caldwell Counties. A search warrant was obtained by the Caldwell County Sheriff’s Department for the property in Braymer.

Rob Chupp, an employee of Diemel’s Livestock, last spoke to the brothers at 11:00 a.m. on July 21, while they were at the 78-acre farm in Braymer. There appeared to be no problems and it was a routine visit.

“Nick and Justin are the kind of people that if they don`t get back in contact with you within the first 2-4 hours we know something is wrong,” Chupp said.

Suspect Arrested

One of the occupants of the property in Braymer, Joey Nelson, previously pleaded guilty to a cattle fraud scheme that occurred between April 1, 2013, and June 2014, according to the Department of Justice. He was sentenced to 2 years in prison and ordered to pay restitution.

On July 26, Nelson, 25, was charged with one felony count of tampering with a motor vehicle within the jurisdiction of Caldwell County, in connection to the brothers’ rental truck. Authorities took the man into custody on Friday afternoon, according to ABC9. He’s being held without bond.

Authorities were unable to provide more details but did confirm that foul play is involved. The cause of death is undetermined at this time.

When asked by a reporter whether the remains would be described as bodies, the sheriff paused for several seconds before responding, “Human remains.”

Anyone with any information is urged to contact authorities at a tip line set up specifically for the case, at 816-632-TIPS.
