ATLANTA (AP) — Police in metro Atlanta say a 52-year-old man killed his two sons and wife and hanged himself in their apartment.

The bodies of Shivinder Singh Grover, his wife, 47-year-old Damanjit Kaur Grover, and their two sons, 5-year-old Gurtej Singh Grover and 12-year-old Sartaj Singh Grover, were found Monday in Johns Creek.

Johns Creek Police Chief Ed Densmore Tuesday said the boys died from wounds to their necks and their mother died from blows to her head. Police and the medical examiner's office would not disclose any additional details, and the motive behind the murder-suicide is unclear.

Police say the slayings were the first homicides recorded in Johns Creek since the city about 25 miles northeast of downtown Atlanta incorporated in 2006.
