Serial shooter sentenced to multiple lifetimes in prison with help from NIBIN

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)

Case details
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.

It is a partnership between ATF; Denver Police Department; Aurora Police Department; Lakewood Police Department; Commerce City Police Department; Thornton Police Department; the District Attorney's Offices for Denver, Arapahoe, Adams, and Jefferson counties; and the U.S. Attorney's Office.
