Defendant: John Walch
NIBIN Impact: If it wasn’t for NIBIN, Walch may not have been definitively identified as the shooter in an attempted homicide in Aurora, Colorado, that left a Good Samaritan paralyzed from the waist down in 2016. Thanks to NIBIN, Walch was also linked to three shootings in neighboring Denver, Colorado.
Defendant convicted of:
- Two counts of attempted first-degree murder after deliberation (one for the Good Samaritan and one for the girlfriend)
- Two counts of attempted first-degree murder – extreme indifference (one for the Good Samaritan and one for the girlfriend)
- One count of first-degree assault with a deadly weapon causing serious bodily injury
- One count of first-degree assault – extreme indifference
- One count of attempted first-degree assault with a deadly weapon causing serious bodily injury
- One count of attempted first-degree assault – extreme indifference
- One count of third-degree assault knowingly or recklessly causing injury
Sentence: 192 years
On Jan. 8, 2016, a Good Samaritan in Aurora, Colorado, was shot and paralyzed in a hotel room by an unknown man after the Good Samaritan sheltered a battered woman he found on a sidewalk. The woman, who later turned out to be the shooter’s girlfriend, left with the shooter. When the shell casings were entered into NIBIN, they hit to a December 2015 shooting into an occupied building in neighboring Denver. The same firearm would hit in NIBIN twice more in shots fired cases in Denver between February and April 2016.
On April 27, 2016, Denver Police arrested John Walch in his hotel room after he had been identified in an armed robbery in March. A later search recovered a pistol that hit to the four shootings, including the attempted murder. DNA evidence also tied Walch to the scene of the attempted murder, but with the confirmation from NIBIN, he was identified as the shooter.
Walch was convicted of all nine counts, June 27, 2017, in Arapahoe District Court for the attempted murder in Aurora. He was labeled a habitual offender and sentenced to 192 years in state prison, Oct. 20, 2017. Walch is awaiting state trial for robbery in Denver, Colorado.
