A woman was hacked to death and a second woman is being treated for stab wounds after a killer who may have used an ax attacked them inside a Brooklyn apartment, authorities said. CBS New York reported the injured woman was hospitalized and listed in critical condition.

The carnage was discovered after the surviving victim hailed an Uber outside the Housing Authority's Bushwick Houses at 1:30 a.m. Saturday and asked to be taken to a hospital.

Police said the Uber driver called 911 and police and medics responded. The woman told them there was a dead body inside her apartment. She told them her own 4-year-old daughter was also in the apartment.
