PIKETON, Ohio (AP) — Authorities in rural southern Ohio are urging residents to be cautious as the search continues for whoever fatally shot eight members of a family at four different properties.

The victims found Friday include seven adults and a 16-year-old boy. They were found in homes near Piketon, about 60 miles south of Columbus.

Authorities say all were shot in the head and that it appeared some were killed as they slept, including a mother in bed with her 4-day-old baby nearby. The infant and two other small children were not harmed.

Authorities say the victims are members of one family. Investigators say none of the deaths appeared self-inflicted, so they believe at least one assailant is at large.

A 4-day-old baby and two other small children survived. Reader says more than 30 people have been interviewed as part of the investigation.

Law enforcement officials say whoever is responsible should be considered armed and dangerous.

Meanwhile, Georgia authorities say a man suspected in two shootings that left five people dead has been found dead of an apparent self-inflicted gunshot wound.

Captain Andy Shedd with the Columbia County Sheriff's office says 50-year-old Wayne Anthony Hawes' body was recovered today by authorities in his northeastern Georgia home. Shedd says the Friday night shootings stem from a domestic dispute that left three men and two females dead.

Police say three people were shot at one location in Appling and two others were shot dead at another location about a mile away.

The victims include 75-year-old Roosevelt Burns, 85-year-old Rheba Mae Dent, 31-year-old Kelia Clark, 59-year-old Lizzy Williams and 62-year-old Shelly Williams. Police believe some of the victims were related to the suspect's wife.
