Investigators say there appears to have been a “violent struggle” inside the apartment.

“Since this females body was blocking the door to get in the property, police actually called the fire department to get a ladder and the police officer climbed up to the second floor, went inside the window, so not to disturb the scene, that’s when he discovered the bloody scene also discovered the knife,” Chief Insp. Scott Smalls said.
