Paul's daughter, Sarah Skiba, was visiting him during the weekend of February 7, 1999 at his home in Thornton, Colorado. Paul and Sarah's mother, Michelle Russell, are divorced and it was Paul's scheduled visitation with his daughter at the time. Sarah resided in Granby, Colorado with her mother in 1999. Paul owned Tuff Movers, a moving company based in Westminster, Colorado. He and Sarah were last seen at approximately 6:00 p.m. on February 7, 1999 in Littleton, Colorado. Sarah accompanied Paul and his employee, Lorenzo Chivers, to the city for a moving job at the time. None of them have been heard from again.

Russell reported her daughter as a missing child to authorities when she failed to return home from her father's visitation. Investigators initially believed that Paul had abducted Sarah with Chivers's assistance. A warrant was issued for Paul's arrest and authorities thought the disappearances were related to a possible custody dispute.

The investigation changed direction when Tuff Movers vehicle, a white 1978 Chevrolet moving truck with red crescents painted on both sides, was located shortly after Russell contacted authorities. A photo of the truck is posted below this case summary. Investigators discovered the vehicle had been abandoned in the Westminster parking lot used by Paul's company. The truck was riddled with bullet holes and was smeared with blood and a piece of human scalp with hair attached was inside; shell casings and blood were found in the lot as well. There was no sign of Sarah, Paul or Chivers at the scene. Chivers's car was found parked in the lot, but Paul's vehicle was located in Denver, Colorado. DNA tests performed on the blood in April 1999 found on the truck's door was proven to be Paul's type. Authorities changed the classification of the missing persons' cases at that time to Endangered Missing and announced that foul play was suspected in the disappearances.

The truck's 3 x 10-foot metal ramp was not located with the vehicle. Authorities believe that the ramp may contain evidence related to the cases. Investigators were continuing to search for the ramp in February 2002.

Investigators dredged several lakes around the Denver, Colorado area in an effort to locate Sarah, Paul and Chivers's remains. No evidence was produced during the searches. It was believed that authorities were preparing to make an arrest in connection with the cases in August 1999, but the report proved to be false. No one has been charged with any involvement in any of the disappearances, but in 2005 authorities renewed the investigation into their presumed murders.

Some agencies may continue to refer to Paul and Chivers as "abductors" in Sarah's case; the classification has changed, however.
