In a case that unfolded in Jackson County, Indiana, authorities uncovered a complex murder and conspiracy involving poison and a planned hit list following a burglary in September 2023. The investigation began when Marsha Allen’s home security footage captured Steven White, identified as a friend of her daughter, Ashley Jones, burglarizing the home. White later implicated Marsha Allen in the murder of her husband, Harold Allen, and revealed a wider plot involving multiple poisoning attempts and a subsequent hit list.
Harold Allen had died a year earlier in December 2022, initially attributed to cardiac issues. According to police, Marsha Allen and Ashley Jones had repeatedly tried to kill Harold with various exotic poisons. When earlier attempts failed, they allegedly turned to ethylene glycol, an antifreeze ingredient, which was secretly administered through a root beer float served by Marsha Allen on the day of his death.
During interrogation, Steven White confessed to the burglary but also disclosed Marsha’s involvement in Harold’s death, implicating Ashley Jones as the mastermind behind both the murder and the burglary. Authorities uncovered thousands of incriminating text messages between Marsha Allen and Jones that detailed the poisoning plans and conspiracies.
A month after the burglary, Marsha Allen denied involvement in her husband’s death but tragically took her own life shortly after police questioning. Ashley Jones was charged with Harold Allen’s murder and jailed. While awaiting trial, she reportedly provided her cellmate with a “kill list” containing names of people who had knowledge about the murder. Investigators believe the list targeted witnesses Ashley intended to eliminate, starting with Steven White, who had been charged with burglary.
Jackson County law enforcement expressed confidence that Jones would have acted on the list if able. However, no charges were filed related to the hit list, though handwriting analysis suggested Jones likely authored it.
In August 2025, Jones accepted a plea deal, pleading guilty to attempted murder and conspiracy to commit murder, resulting in a 50-year prison sentence. Steven White received a sentence of three and a half years for his role in the burglary.
Why it matters
This case highlights the intersection of poisoning as a method of domestic murder and the lengths defendants may go to obstruct justice, including soliciting violence against witnesses. It also underscores the role of digital evidence, such as text messages and home surveillance, in unraveling modern criminal conspiracies.
Background
Poisoning cases are traditionally challenging due to the difficulty of detection and proving intent. The use of what appeared to be a benign root beer float as the vehicle for a lethal dose added a unique element to this investigation. Furthermore, the familial relationship between the accused and victim, along with involvement of close associates, reflects common complexities in domestic homicide cases.
