Christie Wilson, a 27-year-old from San Jose, California, disappeared from the Thunder Valley Casino in Lincoln on October 5, 2005; the man last seen with her, 53-year-old Mario Flavio Garcia, was convicted of her murder in 2006 in Placer County’s first no-body homicide prosecution, and her skeletal remains were finally recovered from his former Auburn property in August 2020. The Christie Wilson murder case is one of the rare California prosecutions that secured a first-degree murder conviction, and later a body, entirely through circumstantial and forensic evidence.
The Night She Disappeared
Wilson had driven to the Sacramento area on October 4, 2005, to pick up belongings from her ex-boyfriend, Danny Burlando. That evening she went to Thunder Valley Casino to play blackjack. Surveillance footage captured her at a table beside Garcia, who talked with her over several hours. Her phone was later found under the table.
At 1:13 a.m. on October 5, the video showed Wilson and Garcia walking out of the casino together. Garcia tried to put his arm around her, and she firmly pushed it away. They disappeared into the parking lot. About three minutes and forty-one seconds later, Garcia’s car came back into camera view, apparently with him alone inside. Wilson’s car stayed in the lot.
Burlando reported her missing on October 6 after finding her car still parked at the casino. Detectives briefly looked at him and cleared him. Casino player-card records identified the man on the footage as Garcia.
How Investigators Built a Case Without a Body
When officers interviewed Garcia four days after the disappearance, they noted fresh scratches on his face and chest. Garcia blamed poison oak and a fall while trimming a tree. An emergency room doctor who had sat at the same blackjack table testified he saw no such injuries on Garcia earlier that night.
Garcia’s car produced the strongest physical evidence. Investigators found hair consistent with Wilson’s wedged in an exterior door handle, in the trunk, and in the backseat. Small amounts of blood containing a mixture of Wilson’s and Garcia’s DNA were on the backseat and a door. The appellate court later observed that the placement of the hair in the door handle “required force to dislodge” it from Wilson’s head and “force to embed” it in the handle, pointing to a violent struggle.
Digital evidence added to the picture. In the week after Wilson vanished, Garcia ran Google searches for “forensics,” toxicology terms, and information on date-rape drug testing. He researched California statutes on search warrants and legal privileges and printed out documents on those subjects. Police recovered a deleted self-portrait Garcia had taken on October 9 showing injuries to his face, forehead, and neck. A search of his home also turned up a handgun he was prohibited from possessing because of a prior felony.
Garcia was arrested on a weapons charge. Three weeks after Wilson disappeared, prosecutors charged him with her murder, still with no body.
Garcia’s History of Violence Against Women
In December 1978, Garcia kidnapped and raped a woman named Wendy Ward in Alameda County. Prosecutors initially recommended charges of kidnapping, two counts of forcible rape, burglary, and assault with a deadly weapon. Garcia ultimately pleaded guilty to a single count of assault with a deadly weapon and received probation.
On Christmas Day 1979, Garcia’s then-girlfriend Lynette Smith and her mother Violet Davis died when their car went into the Oakland Estuary. Garcia swam to shore and told investigators Smith had been driving. Oakland police could not prove who was behind the wheel and never filed charges; the deaths remained an open case.
During the Wilson investigation, deputies found a gold watch in Garcia’s possession that had been stolen from Ward years earlier. The 1978 assault conviction would become important at sentencing.
The Conviction and Sentence
Garcia’s murder trial began on September 11, 2006, moved from Placer County to Sacramento County. Deputy District Attorney Garen Horst led the prosecution, with Sacramento County District Attorney Anne Marie Schubert assisting on DNA evidence. The trial ran two months and included roughly 90 witnesses.
The prosecution’s theory was felony murder based on kidnapping. Horst argued that Garcia met Wilson at the blackjack table, left with her, subdued her at or near his vehicle, killed her, and disposed of her body. The surveillance video, the forensic evidence, the suspicious injuries, contradictory statements, and internet searches carried the case. Garcia told investigators he had turned left leaving the casino, the most direct route home, but the footage showed him turning right.
Garcia testified in his own defense, denied any involvement, and suggested Wilson’s boyfriend was responsible. His attorneys argued the evidence fell short of murder and that Wilson could still be alive.
In November 2006, the jury found Garcia guilty of first-degree murder and possession of a deadly weapon, a collapsible baton found in his vehicle. At sentencing on January 11, 2007, Placer County Superior Court Judge Larry D. Gaddis imposed 25 years to life for the murder, doubled to 50 years to life under California’s Three Strikes law because of the 1978 assault conviction. A consecutive four-year term on the weapons charge brought the total to 59 years to life.
Garcia used his allocution to declare his innocence. “I suppose that at this hearing, I’m supposed to ask for mercy, for forgiveness and to show remorse. However… I will not do such thing… I did not kill Christie Wilson. I am innocent,” he said.
The Appeal
Garcia appealed to the Third District Court of Appeal, arguing evidentiary and instructional errors and contending the evidence supported at most involuntary manslaughter. He also argued the prosecution had improperly used his refusal to be photographed and his decision to end a police interview as evidence of consciousness of guilt, in violation of his Fourth and Fifth Amendment rights.
On February 25, 2009, a three-judge panel affirmed the conviction. The court agreed that the trial judge had erred in allowing prosecutors to use Garcia’s assertion of his constitutional rights against him, but found the error “harmless beyond a reasonable doubt,” citing “overwhelming evidence” of consciousness of guilt from the injuries, contradictory explanations, internet searches, and forensic findings. The panel held there was sufficient evidence of first-degree murder on a felony-murder theory predicated on kidnapping. The California Supreme Court denied review on June 10, 2009.
Finding Christie Wilson After Fifteen Years
Wilson’s mother, Debbie Boyd, and stepfather Pat Boyd, a former San Jose police detective, spent fifteen years pushing to recover her remains. Placer County District Attorney investigators Don Murchison and Nuno Tavares worked the case throughout, searching abandoned mines, septic tanks, and other sites without result.
The break came in 2019, when Murchison and Tavares interviewed Garcia’s sons, Kris and Andy, who had not previously cooperated. Kris, who was 19 when Wilson disappeared, recalled seeing his father working a tractor on the family’s Auburn property in the days afterward with a “crazed look in his eyes.” The activity struck him as strange because Garcia was supposed to have been at a soccer game. Kris pointed to a specific area near a detached garage.
In August 2020, investigators returned to the roughly five-acre former Garcia property in Auburn with permission from the current owners. Ground-penetrating radar identified eight potential voids under the surface. The first two excavation sites turned up nothing. At the third, the area Kris had described, investigators found a human bone and eventually recovered nearly Wilson’s entire skeleton, buried about 100 yards from the house near the detached garage.
Dental records confirmed the remains were Wilson’s. An autopsy showed a broken nose and a broken hand, injuries consistent with a violent struggle. The skeletal condition prevented an exact cause of death from being determined.
Murchison and Tavares flew to Scottsdale, Arizona, where Debbie Boyd had moved, to tell her in person. Years earlier, she had told a class of homicide investigators, “Please don’t ever just call me on the phone.” Pat Boyd said of the recovery: “They brought two people home. They brought my daughter home. They brought my wife home.”
What Happened to Mario Garcia
Mario Flavio Garcia died on December 24, 2020, at 12:45 p.m. at an outside medical facility while incarcerated at the Richard J. Donovan Correctional Facility in San Diego. He was 68. The San Diego County Medical Examiner’s Office attributed his death to complications from COVID-19, with lung cancer as a significant contributing condition. He never admitted guilt in the murder of Christie Wilson.
