Investigators say four people found dead inside a Texas home were members of the same family and that all were shot.

Fort Worth police said in a news release Tuesday that the bodies of the man, woman, boy and girl were found in the home in a residential development in the northern part of the city. Police haven't specifically said that the four were shot to death.

The circumstances around their deaths remain unclear and police spokesman Buddy Calzada says no determination has been made on whether it was a murder-suicide. Authorities say they're not looking for any suspects.

Officers went to the home Monday after receiving a call about the family. Authorities have released few details and have not released the names or ages of the family members.
