Jefferson County authorities arrested two suspects Sunday afternoon who are believed to be involved in a possible homicide.

Just after 5:30 p.m. on Sunday, a stand-off negotiator talked Jerry Gilbert, 25, and Caitlyn Grable, 21, both from Odessa, TX, out of an occupied house at 1504 D Street in Fairbury.

Continued investigation determined that Justin Crenshaw, who was previously being sought in this case, was not involved in the incident.

Several houses in the area were evacuated as a perimeter was set up. Jefferson County was assisted by the Thayer County Sheriff's Office and the Nebraska State Patrol.

On July 4, Jefferson County authorities were given information on a possible homicide that took place on July 1st at Crystal Springs Park in Fairbury.

On July 6, just after midnight, a suspect vehicle was located by a trooper with the Nebraska State Patrol, and the driver, 23-year-old Trey Saathoff of Diller, was arrested on drug charges.

Evidence was found in both the vehicle and at the crime scene, but as of Sunday evening, a victim has not been identified or located.

Officials also haven't located a suspect vehicle, which is described as a Silver Honda with Texas license plates.

Jefferson County Sheriff Nels Sorensen said that several banks in Fairbury were being monitored Sunday, because authorities believed Gilbert and Grable would possibly try to rob a bank before they left town.

Anyone with any information is encouraged to contact Jefferson County authorities or the Nebraska State Patrol. Sorensen does not believe there is an ongoing threat to the public at this time.
