Florida police said a three-month-old woman and child were found shot dead inside a house and an armed suspect was arrested shortly thereafter.
The Gainesville Police Department said Kevi Ellis, 26, surrendered to the police officers after they arrived at the scene.
The woman and child have not been identified, and it is not clear if they had anything to do with the suspect. Officials say two other children were found hiding under a bed.
The authorities have not revealed any motive.
