The rape and murder of Angie Dodge occurred in Idaho Falls, Idaho, on June 13, 1996. The true perpetrator was apprehended in May 2019, nearly 23 years after the crime was committed.

Chris Tapp served 20 years in prison after being convicted of Dodge's rape and murder, based upon faulty evidence and a coerced confession. At the same time, authorities continued to search for other suspects whose DNA would match that which was left at the crime scene. In 2017, Tapp's rape conviction was vacated, and he was released from prison.

In 2014, Michael Usry Jr. was accused of rape and murder after he was identified as a suspect through Y-chromosome familial searching, a process by which partial DNA matches to relatives are used to identify an individual. After conducting a proper DNA test, though, authorities discovered that Usry did not match the DNA found at the crime scene, and charges against Usry were dropped.

In 2019, authorities used investigative genetic genealogy to identify Brian Leigh Dripps Sr. He was later found to have a full genetic match to the CODIS profile, and confessed to the crime after interrogation; he was ultimately convicted.

The case helped bring attention to investigative genetic genealogy, a process wherein searching for relatives in consumer genetic databases leads to the discovery of a suspect. With both false accusations and the ultimate conviction obtained through investigative genetic genealogy, the case is an example for how non-criminal genetic repositories are used in criminal investigations, and furthered the debate on the appropriateness of their use.

In January 1997, about a half year into the investigation, Idaho Falls officials questioned 20-year-old Chris Tapp, initially for information regarding other suspects. After over 100 hours of intense police interrogation, Tapp confessed to the crime under heavy pressure, although no physical evidence tied him to the scene and his confessions were inconsistent and contradictory. Tapp was convicted in May 1998 for aiding and abetting Dodge's rape and murder, and sentenced to a minimum of 30 years in prison.

In 2001, Tapp recanted his confession and claimed he was coerced by police and fed information about the crime. In 2007, after Tapp had served ten years in prison, his case was revisited by the Idaho Innocence Project. A professor and undergraduate at Boise State University who worked with the project reviewed Tapp's interrogation tapes and arrived at the conclusion that Tapp had been heavily coerced into his confession. Tapp's case was appealed in 2017 and the rape charge was rescinded, lessening his sentence from 30 years to 20 years. Tapp had by then served his full 20-year sentence and was released.

In July 2019, Tapp was exonerated for the murder charge, after Brian Leigh Dripps Sr. was arrested as a suspect for Dodge's murder. In October 2020, Tapp sued the city of Idaho Falls for wrongful conviction. In June 2022, a settlement was reached for $11.4 million.
