Heather Rose Rich, a 16-year-old Waurika, Oklahoma high-school cheerleader and honors student, was in emotional distress in the weeks before her death, having recently broken up with boyfriend Randy Wood and lost an acquaintance, Dennis Wayne Goss, to suicide. On the night of October 2, 1996, following a family argument, Rich slipped out of her bedroom window before midnight to meet 17-year-old Joshua Bagwell for a first date. Bagwell was accompanied that night by 19-year-old high-school dropout Curtis Gambill and 17-year-old Randy Wood, Rich's recent ex-boyfriend. The three teenagers plied Rich with alcohol until she was intoxicated, raped her while she was incapacitated, then drove her to a bridge over Belknap Creek in Montague County, Texas, shot her nine times, and threw her body into the creek below.
When Rich did not return home, the Jefferson County Sheriff's Department initially declined to treat her as missing, suggesting she had run away. Her mother, Gail Rich, refused to accept this explanation and canvassed the community herself. On October 9, 1996, a Texas rancher and his granddaughter discovered Rich's body floating in Belknap Creek; she was identified the following morning primarily by a signet ring, as her face had been disfigured by gunshot wounds.
A joint investigation involving Montague County, Texas, authorities, the Jefferson County, Oklahoma, Sheriff's Department, the FBI, and the Texas Ranger Division followed. Forensic analysis linked the shotgun ammunition used in the killing to a purchase made by Bagwell and Gambill at a Waurika hardware store, and investigators identified Gambill's Mossberg shotgun as the likely murder weapon. Bagwell, Gambill, and Wood were arrested on October 24, 1996, and charged with first-degree murder the next day. Bagwell gave no statement to police; Gambill and Wood gave differing, self-serving accounts implicating one another.
Gambill was tried first, in Fort Worth, Texas, after a change of venue. In exchange for a guilty plea and an agreement to testify against Bagwell, prosecutors did not seek the death penalty; Gambill was convicted on October 15, 1997, and sentenced to life imprisonment. At Bagwell's trial in Montague, Texas, beginning February 1998, both Gambill and Wood reneged on aspects of their plea arrangements — Gambill reverting to naming Wood as the shooter, while Wood exposed himself to potential capital punishment by testifying fully against Bagwell. Bagwell was convicted of capital murder and conspiracy to commit capital murder on February 17, 1998, receiving an automatic life sentence plus a concurrent 99-year sentence. Wood was subsequently tried, convicted of capital murder on August 25, 1998, and automatically sentenced to life imprisonment.
All three later filed unsuccessful appeals. In January 2002, while awaiting a separate conspiracy trial, Bagwell and Gambill escaped the Montague County jail with two other inmates, evading capture for nine days before surrendering following a hostage standoff in Ardmore, Oklahoma. Gambill was subsequently convicted of conspiracy to commit murder in relation to the original case in January 2002. Rich's father also pursued a civil wrongful death claim against the hardware store owner who sold the ammunition; courts ultimately ruled in the store owner's favor. As of records cited, Bagwell and Wood are eligible for parole in 2036, and Gambill in 2026.
