A Mesa County judge has ordered a Longmont man to submit DNA and fingerprints to police as part of their investigation into two 1975 stabbing deaths in Grand Junction.
The judge says police want to use a swab to collect cells from 64–year-old Jerry Nemnich's mouth and obtain photos and samples of his handwriting.
It's unknown why authorities want the information.
Nemnich was arrested in April for the slayings of 24–year–old
Linda Benson and her 5–year–old daughter, Kelley.
The two were found dead in July 1975 in their apartment.
Nemnich's arrest affidavit remains sealed.
He is due back in court tomorrow.
