Casa Grande authorities are the death of a teen girl whose dead body was recovered from her family's home on Christmas Day.

The officials are awaiting the autopsy report to determine what killed 13-year-old Aniarael Macias.

They were tipped off about the death by 33-year-old Adam Villa who called 911 on Wednesday night to report his wife had allegedly stabbed him and he was driving himself to a hospital.

Police officers responding to the Colony Apartments found 35-year-old Connie Villa and three of her children -- ages 3, 5 and 8.

The woman also had been stabbed and was taken to a hospital for treatment. The three children didn't appear to be injured.

Police say they found the teenage girl dead in a bathroom.

Ana Mollet is a member of Mothers Of Preschoolers, also known as MOPS. She says Connie Villa belongs to the group and that’s how they met.

Police criminal charges are pending the outcome of the investigation and autopsy.

They say it's still unclear what led to the stabbings.
