Angie Dodge's brutal rape and murder in 1996
In 1996, Angie Dodge was brutally raped and murdered in her Idaho Falls apartment. The crime scene indicated a vicious attack and posed body, pointing to a crime of passion. Police investigations focused on DNA evidence but failed to match it with Angie's acquaintances or her current boyfriend. During this period, DNA analysis technology was still in its infancy.
Carol Dodge's 20-year crusade
Carol Dodge embarked on a two-decade-long quest to find her daughter's killer and to exonerate the falsely accused Christopher Tapp. She became heavily involved in the investigation, conducting her own research, and tirelessly spreading awareness. After doubting Tapp's forced confession, Carol worked closely with DNA and false confession experts, eventually persuading genetic genealogist CeCe Moore to help with the case, despite challenges posed by the degraded DNA evidence.
Identifying and convicting the real killer, Brian Dripps
Genetic genealogy, led by CeCe Moore, was pivotal in identifying and convicting Brian Dripps as the actual murderer. Moore's work, along with a contribution from Parabon Labs, led them to Dripps, who had evaded suspicion despite residing in Idaho Falls during the murder. Dripps confessed to the crime and his DNA match verified his guilt, finally exonerating Tapp as an innocent man. This became a landmark case, showcasing the efficacy of genetic genealogy in solving cold cases and rectifying wrongful convictions.

Angie Dodge's brutal rape and murder in 1996
In the summer of 1996, the community of Idaho Falls was shaken by the brutal rape and murder of Angie Dodge, setting off a chain of events that would reveal the complexities and pitfalls of law enforcement and the justice system.
The crime scene and early investigation
Carol Dodge recounts the haunting day she discovered her daughter's fate, describing it as the moment her "whole system shut down." Newly appointed officer Bill Squires remembers being called to Angie's apartment, marking his first homicide case. What he found was a disturbing scene: Angie Dodge had been viciously attacked, nearly decapitated, with a teddy bear soaked in blood and a bloody handprint on her stomach. However, detectives failed to procure a usable print from the bloody handprint left near the bed.
Despite the lack of a murder weapon or signs of forced entry, critical DNA evidence was left at the scene, signaling a sexual assault. Angie’s body appeared to have been posed, suggesting a crime of passion and an intention to humiliate. Although DNA analysis was relatively new at the time, investigators collected biological materials, certain that it would be the key to solving the case. Crime scene investigator Jeff Pratt emphasized the importance of the DNA evidence, but the lead detectives pursued different leads.
Despite testing the current boyfriend and various friends of Angie who had visited before the murder, none of their DNA matched the evidence found at the scene.
Police zero in on Chris Tapp and his "confession"
The scrutiny of Angie’s social circle led detectives down to the river, where they interrogated her friends and acquaintances. Amidst growing frustration due to the lack of matches to the DNA found on Angie’s body, Chris Tapp, a friend of the victim, became the focus of the investigation. Tapp, under intense interrogation, confessed to the crime and allegedly admitted to holding a knife during the incident. However, Tapp later shared with interviewer Keith Morrison that he felt scared and coerced into giving ...

Identifying and convicting the real killer, Brian Dripps
The case that confounded authorities for decades took a pivotal turn with the help of genetic genealogy, leading to the exoneration of the wrongly convicted Christopher Tapp and the identification and confession of the real killer, Brian Dripps.
Genetic genealogy leads police to prime suspect Dripps
Genetic genealogy expert CeCe Moore dove into the cold case at the request of Carol Dodge. Moore and a team from Parabon Labs, including utilization of their ability to sketch a suspect from DNA, began to unravel the layers of genetic material that would lead them to the perpetrator. After constructing detailed family trees and analyzing commonalities between the DNA profiles, Moore ultimately traced the lineage to a family with the surname Usry, containing six potential male matches, one of whom had resided in Idaho the entire time.
Creative police work ensued, involving the covert collection of a DNA sample that proved non-matching. A breakthrough came when Moore, after contacting a local library, discovered an obituary revealing that a woman's son from a Usry marriage had changed his last name to that of his stepfather's. This led to Brian Dripps, who lived in Idaho Falls in 1996 and was notably absent from the suspect list despite being under suspicion just after the crime.
Dripps confesses and says he acted alone
Upon confirmation of a DNA match from a cigarette butt discarded by Dripps, detectives brought him in for interrogation. Under questioning, Dripps confessed to the murder of Angie Dodge, admitting he was under the influence of drugs and alcohol at the time of the crime. He clarified that he accessed Dodge's home through the door and believed she was deceased when he left. Cru ...
