On Tuesday night police were dispatched to Tasha Haefs’ home after she called 911 and told the despatcher ‘the devil was trying to attack her,’ instead responding officers found blood on the front steps of the home on arrival.
Officers could hear a woman singing, but she refused to open the door, prosecutors said. The officers said the louder they knocked, the louder the woman sang. 

One officer looked in through a window saw what appeared to be a decapitated head inside the house and police, who knew multiple children lived in the residence, forced their way in.  
Once inside, police found Haefs with blood on her legs and feet. 
‘The female suspect had apparent blood on her person and two knives with apparent blood on them were observed in plain view throughout the residence,’ the criminal complaint said.

‘The community now knows some of the terrible details of the death of this 6-year-old child. It takes our breath away,’ she said. ‘My office, as it always has, pledges to do everything in its power to bring justice in this young boy’s murder. We will not shrink from our responsibility.
