Nelson was already facing charges in connection to their case. He faced tampering with a vehicle after authorities said he drove a truck the brothers rented from his farm to a commuter parking lot, where it was found abandoned.

He remains jailed in Caldwell County without bail.

This isn’t the first time he’s been in trouble with the law.

Nelson also faces charges in Kansas of endangering the food supply. Prosecutors there say Nelson didn’t have proper health papers in May when he took 35 calves from his family’s farm in Missouri to a farm in Fort Scott, Kansas.

Nelson was sentenced in 2016 to two years in federal prison for selling more than 600 head of cattle that didn’t belong to him. He pleaded guilty to cattle fraud that caused more than $262,000 in losses. He was released in March 2018.

Nelson also pleaded guilty in August 2015 to two misdemeanor counts of passing bad checks.
