Former Boulder police detective Steve Thomas has broken nearly three decades of silence to name the killer he believes murdered six-year-old JonBenét Ramsey.
Thomas, who spent years on the case before quitting, points directly at the child’s mother, Patsy Ramsey, in a new book titled *JonBenet: Inside the Ramsey Murder Investigation*. The former detective alleges that Patsy, then approaching her 40th birthday, strangled her daughter in a panic after an explosive confrontation over bed-wetting left the girl with a serious head wound.

Thomas wrote that the deadly sequence began with stress compounded by “an approaching 40th birthday, the busy holiday season, an exhausting Christmas day and an argument with JonBenét over a bed-wetting incident.” He claims this pressure led to “some sort of explosive encounter in the child’s bathroom” that caused JonBenét to fall unconscious from a head injury.
Rather than seeking medical help, Thomas alleges, Patsy Ramsey improvised a kidnapping scenario. She wrote a ransom note, then faced what Thomas described as “a major problem of what to do with the body.” The former detective contends the accidental injury transformed into murder during this cover-up attempt.
“Only feet away was her paint tote,” he wrote. ”She grabbed a paintbrush and broke it to fashion the garrote with some cord. Then she looped the cord around the girl’s neck.”
Thomas further alleges that JonBenét’s father, John Ramsey, discovered what happened but “chose to protect his wife” instead of contacting authorities. The former detective’s theory marks the first time a law enforcement official involved in the case has publicly accused a Ramsey family member.
Patsy Ramsey’s attorney, L. Lin Wood, immediately rejected the claims. Wood called Thomas’s account “fiction and utter nonsense,” adding that the former detective’s theory “is refuted in its entirety by medical evidence.”
Other investigators who worked the case also appear to distance themselves from Thomas’s conclusions. Veteran homicide detective Lou Smit, another key figure on the case, maintains the intruder theory. Thomas himself acknowledged in his book that Smit believes a stranger strangled JonBenét “in some sort of autoerotic fantasy” before concealing her body in the basement, where John Ramsey found his daughter the following morning.

The Ramseys, for their part, have pushed back through their own book, *Death of Innocence*, released last month. In it, both Patsy and John Ramsey reaffirm their belief that an intruder killed their daughter.
Legal consequences from any theory appear remote. Boulder district attorney Alex Hunter reviewed the various claims and dismissed a grand jury after 13 months without returning any indictments. Hunter also criticized Thomas’s public statements, saying it “is improper in my judgement for a cop to be talking about confidential information in an ongoing case.”
Thomas’s allegations have never been formally filed against the Ramsey family and remain his personal opinion. The case, which began on Boxing Day 1996 when the child beauty queen was found dead in her family’s Boulder, Colorado basement, continues to rank among America’s most notorious unsolved murders.
