The Thomas Randolph Case — Nevada's 'Black Widower' Murders

The Case

The Thomas Randolph case is a Nevada double murder prosecution that earned its defendant the moniker "black widower" due to his history of six marriages and four deceased wives. On the evening of May 8, 2008, two people died in Thomas Randolph's Las Vegas home: his sixth wife, Sharon Causse Randolph, and a man identified as Michael Miller. Randolph claimed he had shot Miller in self-defense after Miller, whom he described as a masked intruder, had murdered Sharon. Prosecutors, however, argued that Randolph had orchestrated the entire scene, hiring Miller to kill his wife and then murdering Miller to eliminate the witness and collect insurance money.

The case would wind through the Nevada court system for more than 15 years, resulting in two separate murder convictions, a death sentence, a successful appeal to the state's highest court, and ultimately a 60-years-to-life prison sentence handed down in 2024. The legal saga highlighted complex issues of evidence admissibility, particularly regarding prior bad acts, and captivated true crime audiences who followed the trials through extensive media coverage.

The Crime

On the night of May 8, 2008, emergency dispatchers in Las Vegas received a 911 call from Thomas Randolph. He reported that an intruder had broken into his home, shot his wife Sharon, and that he had shot the intruder in self-defense. When police arrived at the Clark County residence, they found two bodies: Sharon Causse Randolph and Michael Miller, both dead from gunshot wounds.

Randolph's account painted a picture of a home invasion gone wrong. He claimed a masked man had entered their home and opened fire, killing Sharon before Randolph could retrieve his own firearm and shoot the attacker. The scene appeared to support a violent confrontation, but investigators quickly grew suspicious of Randolph's narrative.

Prosecutors would later argue that the entire scenario had been carefully staged. According to the state's theory, Randolph had hired Michael Miller to murder Sharon, with plans to then kill Miller and claim self-defense against a random home invader. The motive, prosecutors alleged, was financial: Sharon was insured, and Randolph stood to collect substantial life insurance proceeds upon her death. The staged home invasion would allow him to eliminate both his wife and the hired killer while positioning himself as a victim and hero who had defended his home.

The Victims

Sharon Causse Randolph was Thomas Randolph's sixth wife. While the supplied court records do not detail her age or extensive biography, she became the central victim in a case that would expose a disturbing pattern in her husband's marital history. Her death on May 8, 2008, initially appeared to be the tragic result of a random home invasion, but the investigation would reveal a far more sinister plot.

Michael Miller, the second victim, was the man Randolph shot and killed that same evening. Prosecutors identified Miller not as a random intruder but as a hired assassin whom Randolph had recruited to murder Sharon. In the prosecution's narrative, Miller was a criminal instrument who became expendable once he had served his purpose. By killing Miller and framing the scene as self-defense, Randolph attempted to eliminate the one witness who could tie him to Sharon's murder.

What made the case particularly disturbing was Randolph's matrimonial history. Media outlets dubbed him the "Black Widower" after it emerged that he had been married six times and four of his previous wives had died under various circumstances. This pattern became a central element of the prosecution's case, suggesting a history of profiting from the deaths of spouses, though the admissibility of this evidence would later become the subject of intense legal debate.

Investigation

The investigation into the May 8, 2008 deaths began immediately after Randolph's 911 call. While Randolph's self-defense claim initially seemed plausible, detectives in Clark County quickly identified inconsistencies in his account and physical evidence at the scene that contradicted a random home invasion.

Forensic evidence played a crucial role in building the prosecution's case. Crime scene analysts examined bullet trajectories, blood spatter patterns, and the positions of the bodies to reconstruct what had actually occurred. Rather than supporting Randolph's narrative of a masked intruder who shot Sharon before being killed in self-defense, the evidence suggested a more calculated series of events.

Investigators also uncovered financial motives. They discovered that Sharon had been insured and that Randolph stood to benefit substantially from her death. This financial angle, combined with Randolph's history of deceased wives, transformed the investigation from a possible home invasion into a suspected murder-for-hire plot.

Perhaps most damaging was evidence linking Randolph to Michael Miller before the night of the shootings. Prosecutors would present testimony and records indicating that Miller was not a random criminal but someone Randolph had contacted and recruited. The theory that emerged was methodical: Randolph hired Miller to kill Sharon, then murdered Miller to silence him and create a self-defense justification.

The investigation also delved into Randolph's past marriages. Detectives found a troubling pattern of insurance payouts following the deaths of previous wives. While Randolph maintained these deaths were accidental or from natural causes, the pattern raised serious questions about whether Sharon's murder was part of a long-running scheme.

Trial and Verdict

Thomas Randolph's first trial took place in 2017 in Clark County, Nevada. The prosecution presented extensive forensic evidence, expert testimony, and details about Randolph's marital history. Critically, they introduced evidence about the death of at least one prior wife, arguing it demonstrated a pattern of behavior. The jury found Randolph guilty of two counts of first-degree murder, and the court sentenced him to death.

However, the case was far from over. Randolph's defense team appealed the conviction, arguing that the trial court had committed reversible error by allowing the jury to hear evidence about his prior wife's death. In December 2020, the Nevada Supreme Court agreed, overturning the conviction and death sentence. The state's highest court ruled that the prior bad act evidence had been improperly admitted, potentially prejudicing the jury against Randolph by suggesting he was a serial killer of spouses rather than requiring the prosecution to prove the specific charges related to Sharon and Miller.

The case returned to Clark County for a second trial in 2023. This time, with stricter limitations on what prior conduct evidence could be introduced, prosecutors again presented their theory that Randolph had orchestrated a murder-for-hire plot. In August 2023, a new jury reached the same conclusion as the first, convicting Randolph of conspiracy to commit murder and two counts of murder with use of a deadly weapon.

On April 4, 2024, Clark County District Judge Tierra Jones sentenced the 69-year-old Randolph to 60 years to life in prison. While not the death penalty he had originally received, the sentence effectively ensured that Randolph would spend the remainder of his life behind bars. At his age, the 60-year minimum before parole eligibility made it virtually certain he would die in prison.

Today

As of 2024, Thomas Randolph remains incarcerated in Nevada, serving his 60-years-to-life sentence. The "Black Widower" case has become a fixture of true crime media, featured in Investigation Discovery programming and extensively covered by Court TV during both trials. The case raises enduring questions about the balance between admitting pattern evidence to show modus operandi and the risk of prejudicing juries with inflammatory prior bad act evidence.

The Nevada Supreme Court's 2020 decision to overturn the first conviction highlighted the legal complexity of prosecuting defendants with troubling histories. While the pattern of deceased wives appeared highly suspicious and potentially probative of Randolph's intent and planning, appellate courts must ensure that defendants are convicted based on evidence of the specific crimes charged rather than general character evidence suggesting they are bad people.

The successful retrial and second conviction in 2023 demonstrated that prosecutors could prove their case even with more limited evidence about Randolph's past. The forensic evidence, financial motive, and connections between Randolph and Miller proved sufficient for a second jury to conclude that the May 8, 2008 shootings were not a tragic home invasion but a calculated double murder.

For the families of Sharon Causse Randolph and Michael Miller, the 2024 sentencing brought a measure of closure after more than 15 years of legal proceedings. While no sentence can restore their lost loved ones, the conviction and life sentence ensured that Thomas Randolph was held accountable for the murders.

The case continues to generate interest in true crime communities as an example of the "black widower" phenomenon—men who systematically profit from the deaths of multiple spouses—and as a cautionary tale about relationships motivated by financial gain. The Investigation Discovery special examining the case brought the story to a national audience, ensuring that Sharon Causse Randolph and Michael Miller are remembered not just as statistics but as victims of a carefully planned murder scheme.
