CHICAGO -- A man arrested after a woman and three children, including an infant and a toddler, were found shot to death in a Chicago home told police voices encouraged him to kill his family and he was sorry he had run out of bullets, a person close to the investigation told The Associated Press.

Those killed inside a brick home on the city's southwest side early Wednesday included the suspected gunman's wife, his 7-month-old son and his two nieces, said the person who spoke on condition of anonymity because he was not authorized to discuss the investigation. A woman and a teenage boy also were wounded and remained hospitalized.

The Cook County Medical Examiner's office identified the dead as: 7-month-old Jahad Larry, 3-year-old Kelesha Larry, 16-year-old Keyshai Fields and 19-year-old Tawana Thompson Larry.
