A 47-year-old woman was shot three times and killed in a burst of gunfire inside her own Harlem apartment Tuesday afternoon, cops said. 

Basilisa Negron was repeatedly shot inside her home in a residential building on West 141st Street near Malcolm X Boulevard just after 1 p.m., police said.

Cops responded to a 911 call from an unspecified person known to Negron, and found the victim unconscious and unresponsive inside the apartment, authorities and sources said.

Officers and EMS workers rushed into the building, but Negron could not be saved and was pronounced dead on the scene. 

No arrests were immediately made, and the motive remained under investigation hours later.
