The last day anyone saw her
On February 27, 1995, Cynthia St. John was last seen in Fairbanks, Alaska, where she worked at a McDonald’s. Authorities have never found anyone who saw her after that day.
Her parents, Clinton S. “Speck” Watson and Lyla Mae Watson, contacted the Alaska State Troopers that same day to report their eldest daughter missing. Cynthia’s last contact with them had been two months earlier — a call on December 22 from Denver, asking them to wire $500 to her in Fairbanks.
What happened over the next three months turned a missing-person case into a tri-state nightmare.
The husband, the in-laws, and the fourteen-page note
In May 1995, Cynthia’s parents were shot to death in Mississippi, where they lived. Her husband, Roger St. John, was charged with their murders — but police couldn’t find him. A nationwide manhunt stretched all the way to Fairbanks, where he and Cynthia had once lived. Police feared Roger had not only killed his in-laws, but his wife as well.
Later that month, Roger St. John was found dead in a hotel room in Little Rock, Arkansas — suicide by drug overdose. He left behind a fourteen-page suicide note. In it, he confessed to killing the Watsons, writing that they had mistreated his wife and caused her to kill herself. He claimed he had made several failed suicide attempts before.
The note did not say where Cynthia’s body was — because, in Roger’s telling, there was no body to find: his wife, he wrote, had taken her own life.
Investigators never verified that claim. What they believed, instead, was that Roger St. John may have murdered Cynthia too — and taken the location of her remains to his grave in that Little Rock hotel room.
There’s been no sign of Cynthia since February 1995. She is missing under suspicious circumstances, and foul play is suspected.
Theories: what might have happened
Roger St. John killed her. This is the theory investigators have held for thirty years. What supports it: Roger demonstrably killed two people — Cynthia’s parents — in the same season she vanished; his suicide note’s claim that Cynthia killed herself has never been verified by any independent evidence; and no trace of Cynthia has surfaced in three decades. What is unproven: there is no physical evidence tying Roger to Cynthia’s death, no confession covering her, and no body. He is dead and cannot be tried. Presumption of innocence applies to the living; Roger St. John is deceased, and the allegation against him rests on investigators’ stated belief, not a conviction.
The note told the truth — Cynthia died by suicide, and Roger hid it. This is Roger’s own account: that the Watsons’ mistreatment drove Cynthia to take her own life, and his murders were revenge. What undercuts it: nothing in the public record corroborates Cynthia’s suicide — no note from her, no witnesses, no location. A killer’s self-serving letter is the thinnest possible evidence.
She left voluntarily and is living under another name. The faintest of theories, kept alive only by the absence of a body. Against it: Cynthia’s parents reported her missing the day she was last seen; she asked them for money two months earlier, suggesting she was struggling, not planning; and thirty-one years of silence from a woman with living family is not the pattern of a fresh start.
