WESTBOROUGH, Mass. — Seth Mazzaglia, 29, of Dover, N.H., has been charged with second-degree murder in the death of Westborough's Lizzi Marriott.

He will be arraigned in Dover District Court Monday. According to information available online, Mazzaglia is a 2006 graduate of the University of New Hampshire, an actor, choreographer and fourth degree black belt. 

He was featured in an issue of UNH Magazine ballroom dancing with Cassandra Kennet, and is an assistant karate instructor at the Kittery Community Center in Kittery, Maine.

Reporter Betsey Ross commented on Mazzaglia after a Leadership Teacher Seacost retreat at the Rochester Arts House:

"Although it was with the grand entrance of Seth Mazzaglia, Stage Combat Consultant, that the LT group proved to be a slap-happy group – in other words “beating the crap out of each other!” It was also at this point that the group noted that Miss Preston is a natural born actress! The LT Group now has the acting skills needed to star in the next Charlie’s Angels movie!"

Mazzaglia also had roles in multiple movies and plays. Mazzaglia played the role of "lead thug" in the movie "The Present." 

Also, a year ago, Mazzaglia posted on his Facebook page about children avoiding dangerous people.

Police are still searching for Marriott's body. They began searching Peirce Island in Portsmouth late Friday night.
