Two young girls who were found dead on a farm in southwest Colorado have been positively identified as the daughters of one of the suspects.

The bodies of Makayla Victoria Roberts, 10, and Hannah Elizabeth Rosalina Marshall, 8, were found on a 17.49- acre farm south of Norwood in September.

The Sheriff's Office says the fathers of both girls are not involved in the case.

San Miguel County Coroner Emil Sante told 9Wants to Know in September that autopsies have been conducted but that he was awaiting the results of toxicology tests before he could say how the girls died.

On Friday, the Sheriff's Office said the cause of the girls' deaths was still under investigation.
