A 31-year-old man who had been under repeated questioning about the shotgun slaying of Cold Spring police officer Thomas Decker killed himself Wednesday after an hours-long standoff with law enforcement at his home near the central Minnesota city, officials said Friday.
Eric J. Thomes, described at this point by the Bureau of Criminal Apprehension (BCA) as a "person of interest," was found hanged in a metal building near his rural Cold Spring home. Thomes ran into the building when he saw investigators arrive for yet another interview, the BCA added.
Authorities also said that the shotgun used to kill Decker on Nov. 29, 2012, was found on property to which Thomes had access.
