KINGSTON, Mo. (AP) — A judge has set a hearing to determine whether there is enough evidence to try a man for tampering with a vehicle used by two Wisconsin brothers who are missing and presumed dead in Missouri.

Court records show that during a court hearing Thursday, the preliminary hearing for 25-year-old Garland Nelson was set for Sept. 16. Brothers Nick and Justin Diemel, from Shawano County, Wisconsin, were on a trip related to their cattle business when they disappeared last month after visiting Nelson.

Human remains found on a Missouri farm owned by Nelson have not been identified. The tampering charge stems from allegations that Nelson drove a truck the brothers rented from his farm to a commuter parking lot, where it was found abandoned.

Nelson remains jailed without bond.
