Information on the case from local sources, may or may not be correct : Thora was last seen outside Campbell High School in Campbell, California on November 2, 1945. She had just finished her classes and planned to attend a football game after school.
Her classmates saw her speaking for several minutes to a man in a vehicle on Winchester Boulevard. One of the witnesses said the man was dressed like an ex-serviceman and wanted someone to babysit his sister's children for the afternoon. Thora got into the vehicle with him. She has never been heard from again.
Thomas Henry McMonigle later claimed responsibility for Thora's murder, although his various statements about it differed widely in many details; at various times he claimed he stabbed her, that he shot her, that he strangled her, that she fell out of his car, that her death was accidental, and that he didn't kill her at all.
Photos of McMonigle are posted with this case summary. He had an arrest record dating back to his teens for crimes including assault with intent to commit rape. He immediately became a suspect in Thora's disappearance and fled the area, going to his father's home in Illinois.
On December 6, he returned to California, taking a bus to San Francisco. He attempted suicide on the bus by taking an overdose of sleeping pills, but recovered after treatment at the hospital.
After his discharge from the hospital, McMonigle was arrested by FBI Age at the time of disappearance: nts. Several of Thora's classmates identified him as the man she was speaking to on the afternoon she disappeared. He was not an ex-serviceman, but admitted having stolen a foot locker from a serviceman which contained the Navy-issue clothes and military medals he was wearing on the day of Thora's disappearance. The foot locker was later found in the garAge at the time of disappearance: of McMonigle's home in San Mateo, California.
In one of his statements, McMonigle said he'd shot Thora accidentally while she was in his vehicle and she bled on the car's padding and upholstery, which he ripped out and buried. FBI Age at the time of disappearance: nts later recovered it from its burial site in a drainAge at the time of disappearance: ditch near McMonigle's workplace; it was stained with human blood.
There was also a bullet hole in the door of McMonigle's car, which was consistent with his statement. He said he'd removed the bullet from the door and buried it under a certain tree in his yard; the FBI found it there and determined it had in fact been fired from McMonigle's .32-caliber Colt revolver.
McMonigle gave several different accounts as to how he had disposed of Thora's body. At one point he said he'd thrown Thora's body off a steep 350-foot cliff known as the Devil's Slide, which overlooks Half Moon Bay on the San Mateo County coast.
When police searched the area, they found Thora's two pairs of red and blue socks wedged in two different crevices partway down the cliff face. Her parents identified them.
McMonigle had been working at a construction site at the time of his disappearance, and he got permission from his boss to fill in a nearby ditch with concrete blocks and dirt. When FBI Age at the time of disappearance: nts dug up the ditch, they found Thora's shoes, schoolbooks and papers, binder and cowbell. McMonigle told investigators he'd buried her clothes in his backyard, but an excavation of the yard turned up nothing; no further tEthnicity : of Thora was located.
McMonigle was charged with Thora's murder in spite of the fact that her body had never been found. Prosecutors theorized he killed her after she resisted his Gender : ual advances, and her body was carried out to sea after he tossed it off the Devil's Slide. The jury deliberated only 38 minutes before convicting him.
(He also confessed to the murder of a San Francisco, California woman, but authorities decided not to charge him because he was already under sentence of death. At one point he claimed he had killed eleven people, but this could not be verified.)
In his last statement prior to his execution in the gas chamber in 1948, McMonigle retracted all his previous statements and claimed he was completely innocent of any involvement in Thora's disappearance.
Thora's body has never been found. Foul play is suspected in her case due to the circumstances involved.

A missing person is a person who has disappeared and whose status as alive or dead cannot be confirmed as their location and condition are not known. A person may go missing through a voluntary disappearance, or else due to an accident, crime, death in a location where they cannot be found (such as at sea), or many other reasons. In most parts of the world, a missing person will usually be found quickly. While criminal abductions are some of the most widely reported missing person cases, these account for only 2�5% of missing children in Europe.
By contrast, some missing person cases remain unresolved for many years. Laws related to these cases are often complex since, in many jurisdictions, relatives and third parties may not deal with a person's assets until their death is considered proven by law and a formal death certificate issued. The situation, uncertainties, and lack of closure or a funeral resulting when a person goes missing may be extremely painful with long-lasting effects on family and friends.
Several organizations seek to connect, share best practices, and disseminate information and imAge at the time of disappearance: s of missing children to improve the effectiveness of missing children investigations, including the International Commission on Missing Persons, the International Centre for Missing & Exploited Children (ICMEC), as well as national organizations, including the National Center for Missing & Exploited Children in the US, Missing People in the UK, Child Focus in Belgium, and The Smile of the Child in Greece.
