Authorities investigating a woman accused of trying to kill her newborn baby say they have found the remains of another infant in her home.
Police believe the remains had been at Elyse Mamino's home in Belleville, Illinois, near St. Louis, for more than a year.
No charges have been filed in the new development.
Authorities say Mamino gave birth at a house party in November and tried to drown her baby in a toilet.
Emergency responders and a bystander were able to revive the baby girl after someone called authorities. Police say it's not clear if she suffered brain damage.
Mamino was arrested last week and charged with attempted murder. Relatives are caring for the surviving child.
