Massachusetts state and local police have launched a manhunt for Christopher Keely, the suspect identified in the brutal murder of a couple in Marshfield on Wednesday, November 30. 

Plymouth County District Attorney Tim Cruz said officers responded to the home of Carl, 70, and Vicki Mattson, who would have turned 71 on Wednesday, on Gotham Hill Drive at night for a well-being check. That is when they found the married couple dead. Both the victims had been stabbed and bludgeoned.

The suspect is said to have known the couple. However, the relationship between them was not exactly known. The district attorney said investigators had put out an alert to be on the lookout for Keeley. 

“This appears to be a targeted attack against these two individuals,” Cruz told reporters at a news conference Wednesday morning. “The individual that we are looking for right now, we consider him armed and dangerous.”
