It was introduced by Rep. Renny Cushing, a Hampton Democrat whose father and brother-in-law were slain. He said he was outraged when Seth Mazzaglia wanted to skip his sentencing in the death of Elizabeth "Lizzi" Marriott.

  A jury has found Seth Mazzaglia, the 31 year old Dover man accused of killing and raping 19 year old UNH student Lizzi Marriott, guilty of all charges, including first degree murder.  

After Marriott died, investigators found neither Lizzi Marriott’s body, nor any direct evidence of her murder.  A guilty verdict in this trial would depend entirely on the credibility of the crime’s only eyewitness,  Kat McDonough: the now 20-year old ex-girlfriend of Seth Mazzaglia.
