  The defense has rested in the trial of Seth Mazzaglia, the 31 year old Dover man charged with raping and killing UNH student Lizzi Marriott. 

Mazzaglia’s defense team rested after only two days, following 18 days of arguments from state prosecutors-- including extensive testimony by Mazzaglia’s 20-year-old ex-girlfriend, Kat McDonough.  The defendant did not testify on his own behalf.

During the prosecution, the state argued Mazzaglia strangled Marriott. The defense countered that McDonough accidentally asphyxiated Marriott during sex.
