The hunt for the killer of Cold Springs police officer Tom Decker led police to serve a narcotics warrant in Minneapolis this week, but the search didn't lead to any breaks in the case, according to two sources.

Minneapolis police spokesman Bill Palmer confirmed there was a raid Wednesday night at a known drug house in the 2800 block of 14th Ave. S. and that one person was taken into custody and turned over to Bureau of Criminal Apprehension. Palmer didn't know if it was connected to the Decker case.

But two sources tell the Star Tribune it was related to the officer's slaying, but didn't do anything to help solve the Nov. 29 killing.

BCA spokeswoman Jill Oliveria said Friday that investigators have not ruled anyone out as a potential suspect in this case and the weapon believed to have killed Decker, a .20-gauge shotgun, has not yet been located.
