More than a dozen legal, law enforcement and victims' rights organizations say a murder victim's sexual past should remain out of the public eye.

Nineteen-year-old Elizabeth "Lizzi" Marriott, of Westborough, Massachusetts, was a student at the University of New Hampshire when she was killed in 2012. Seth Mazzaglia (muh-ZAYL'-ee-uh) was convicted of her murder and sentenced to life, but he's appealing.

In June, the New Hampshire Supreme Court ruled that information about Marriott's sexual activity that had been sealed during the trial should be made public for the appeal.

On Monday, the New Hampshire Coalition Against Domestic and Sexual Violence filed a brief supporting the Marriott family's request to keep the records sealed.

Oral arguments are set for Sept. 21.
