Kristy Ann Green, a 19-year-old from Sacramento, California, was last seen in March 2000 at her residence on Lock Avenue. Her disappearance, however, did not become an official missing person case for three months. It was only after investigators received a phone call from a man alleging Green had been murdered and her body disposed of that authorities realized she was missing. Following this tip, an investigation was launched, and her case was classified as a homicide.
In July 2000, Green's three-year-old daughter was found at a home in North Sacramento and was placed in protective custody.
The investigation into Green's disappearance led to the arrest of Helen Margaret Tibon and her brother, Kevin Clark, in August 2000. Green had been living with the siblings at the time she went missing, and Clark was the father of her child. The motive for the murder was reportedly to prevent Green from disclosing their involvement in a mail fraud scheme to the police. Green herself had been previously arrested for mail fraud and was bailed out by Clark after spending two months in jail.
During the 2002 murder trial of Tibon and Clark, four of their accomplices testified against them. The testimony provided gruesome details of Green's final moments, stating she was tortured and beaten before being smothered with a tarp. It was alleged that her body was then dismembered, burned, and the remains were placed in a metal drum before being dumped into the Sacramento River. Despite these accounts, Kristy Ann Green's body has never been found.
In his defense, Kevin Clark claimed that the killing was staged to intimidate the four witnesses into silence about their criminal activities. This was the fourth story he had provided regarding Green's disappearance, having previously denied knowledge of her death, then blaming his sister entirely, before admitting his involvement. A jury ultimately convicted both Helen Tibon and Kevin Clark for the murder of Kristy Green, and they were sentenced to 25 years to life in prison. Despite the convictions, the sentencing was delayed for three months due to two individuals claiming to have seen Green alive, though prosecutors dismissed these claims as mistaken identity.Last Seen: Mar 1, 2000
