Police sources said four people were found inside an apartment with gunshot wounds. They were pronounced dead at the scene. 

The victims were identified as two men and two women — a mother and daughter, police sources said. 

Police sources said the daughter’s boyfriend is believed to be the gunman, who called a family member before killing himself. 

The medical examiner’s office will now work to determine the exact causes of death. No further details have been provided.
