The bodies of a woman and her 10-year-old daughter, along with a man with a self-inflicted gunshot wound to his head, were found in a house in the Bronx on Saturday afternoon, the police said.

It was unclear how the woman, Linda Manigault, 34, and her daughter, Heaven Ross, died. The police did not identify the man, 32, who was taken to St. Barnabas Hospital in critical condition. It was unclear what other relationships, if any, there were among the victims.

The two-story house, at 2153 Belmont Avenue, is among the different-colored rowhouses in the Belmont section near the Bronx Zoo.

Heide Sanchez, who lived downstairs from Ms. Manigault, said Ms. Manigault lived with her boyfriend and four children. Ms. Sanchez said Ms. Manigault helped families at a homeless shelter.
