Overview

Angie Dodge, 18, was raped and killed in her first apartment in Idaho Falls, Idaho, in the early hours of June 13, 1996. DNA from the scene came from one unknown man. In January 1997 a 20-year-old acquaintance confessed after more than twenty hours of questioning and seven polygraph sessions, although the DNA was not his, and in 1998 a jury convicted him. Angie's mother, who at first wanted him executed, came to believe the confession was false, helped win his release in 2017, and kept pressing the police to identify the DNA. In 2019 genetic genealogy led to Brian Leigh Dripps Sr., who in 1996 had lived directly across the street and had been spoken to by officers five days after the murder. He confessed, the convicted man was exonerated in July 2019, and Dripps pleaded guilty in 2021 and was sentenced to 20 years to life.

How it was solved

Semen left at the scene gave police a single male DNA profile in 1996, but it matched none of the dozens of local men sampled and, later, nobody in the national criminal database. Police have said evidence and tips at the time suggested more than one attacker, and that theory allowed a 20-year-old acquaintance to be charged on the strength of a confession even though the DNA excluded him. Experts who later reviewed the recorded interrogations and polygraph sessions said he was threatened with the gas chamber, told he had repressed the memory, promised immunity that was then withdrawn, and shown details of the scene; the Idaho Falls police have denied wrongdoing, and courts upheld the confession for years. In 2014 police ran the profile's Y-chromosome markers against a genealogy database later bought by Ancestry and got a 34-of-35 match to a Mississippi man; his son, a New Orleans filmmaker, was swabbed under a warrant and cleared in January 2015. In November 2018 the department turned to Parabon NanoLabs for genetic genealogy on a badly degraded sample. The family tree was the same one, on a branch that had split off more than a century earlier, and it produced six candidates. When the nearest was ruled out by DNA from discarded chewing tobacco, and proved more distantly related than expected, genealogists found an obituary showing a seventh man born after a brief marriage and raised under his stepfather's surname: Brian Dripps. Utility records and a pawn receipt put him at 459 I Street, across from Angie's apartment at 444, from April to August 1996, and the file held a canvass note of his account from June 18, 1996. Detectives recovered a cigarette butt he threw from his car in Caldwell on May 10, 2019; the state laboratory reported a match the next day, the first in more than 100 samples. He was arrested on May 15, 2019, and after about five hours admitted the rape and killing, saying he acted alone.
