Marshfield double murder suspect waives extradition after being captured in Florida

MIAMI, Fla. — A man suspected in the brutal murder of a Marshfield couple waived his extradition in Florida on Monday and will be returned to Massachusetts to face charges.

Christopher Keeley, 27, appeared in a Miami courtroom via a video call on a fugitive from justice charge, just days after he was taken into custody in connection with the murder of Carl and Vicki Mattson, a couple in their 70s.

Plymouth District Attorney Tim Cruz said both victims were found “bludgeoned and stabbed” when police conducted a wellness check at their home last week. Their dog was also discovered dead in the house, and their Jeep Wrangler was recovered in the parking lot of a Walmart in Avon.

Boston 25 also learned that Keeley had Carl Mattson’s credit cards and was using them after the murder.

Keeley was picked up in Miami Beach Friday, after getting into an altercation and allegedly hitting a man in the head with a hammer.

In court, a contentious Keeley told the judge he was ready to stop running.

Keeley: “I waive extradition.”

Judge: “You want to waive?”

Keeley: “I want to waive extradition.”

Judge: “That’s a good choice.”

Boston attorney Peter Elikann agrees. “The only way you can fight extradition, you have to prove, ‘No this is crazy, this is mistaken identity, I’ve never been in Massachusetts, and you simply have the wrong Chris Keeley.’ That would be the only way to argue you have the wrong person,” Elikann said.

Now that Keeley has waived extradition, the path is clear for his return to Massachusetts to face justice for what happened here at the Mattson’s home in Marshfield.

Massachusetts authorities now have 15 days to return Keeley to the Bay State.

There’s no date set on when he’ll appear in a Massachusetts courtroom for arraignment.

Attorney Elikann does not expect bail will be an option for him.

“It’s just not realistic he would be released prior to trial. The allegations are too serious and the idea that he would be risk of flight and too dangerous to be out there among the public, those arguments are so very strong in this case that I don’t see him having chance of being released prior to trial,” Elikann said.

Elikann believes a mental health evaluation for Keeley is likely.
