A New York City man faces charges that he slaughtered his girlfriend and her two young children in a frenzy at their Brooklyn home.
Jermaine Ruiz was charged Saturday with three counts of murder.
The 24-year-old had been in custody since Friday.
Investigators say they believe the killings happened Wednesday night, when neighbors overheard the couple fighting.
Police say that Ruiz spent a day in the apartment with the three corpses and then phoned his father and told him what he'd done.
When officers arrived at the house, they found a bloody scene.
The woman, 22, and her children were dead of stab sounds. The kids were aged two and five. All three had been partly wrapped in plastic bags.
Authorities have yet to release the victims' names, pending family notification.
A knife hasn't been recovered, but police were still actively investigating the scene, NYPD's deputy chief for public information Paul J. Browne said.
