HOUSTON (AP) — The bodies of five people, including three young children, were found Saturday afternoon on a sprawling property with several structures in northeast Houston, police said.

A neighbor made the grisly discovery after seeing a man's body on a porch next to a .22-caliber rifle, investigators said.

The bodies of a woman between 20 and 30 years old and a boy thought to be about 10 were found in one part of the home, said Houston police Sgt. John Chomiak.

The bodies of a young boy and girl were found in another part of the home, described by authorities as a simple wooden structure divided in the middle by the porch.

Investigators declined to speculate on the causes of death, although they said there were no obvious signs of a struggle. They also declined to release identities of the victims.
