Court documents revealed new information on the Bronx man accused of murdering a woman in Washington Heights.

Officials say Tyquane Jemmott, the Bronx man charged with stabbing a woman to death in Washington Heights Monday, jumped out from hiding and ambushed the victim as she left her home.

Court documents say she named her attacker before she died. It also says the victim's sister found her covered in blood and that's when the victim said, "Ty did this to me."

Officials note that Jemmott was the victim's ex-boyfriend.

Jemmott is charged with second-degree murder.
