Rockford Police detectives have recovered a handgun and evidence while following up on leads during the investigation of a Dec. 20 quadruple murder in the 3200 block of Montrose Ave.

According to police, detectives have searched several houses in the area and recovered the handgun and other evidence during those searches. The items will be examined by Rockford Police crime scene detectives and the Illinois State Crime Lab.
