MARSHFIELD — Authorities have identified the victims in a double homicide that took place Tuesday night, and are asking for the public's help in finding the suspect.

State police and Plymouth County District Attorney Tim Cruz said 27-year-old Christopher Keeley is being sought in connection to the double homicide, in which elderly couple Carl and Vicki Mattson lost their lives.

The pair, both in their 70s, were found bludgeoned and stabbed to death in their Gotham Hill Drive home Tuesday after police were called for a wellness check just before 9:30 p.m., Cruz said at a press conference Wednesday.
