Six people were believed to have been killed at a rural Texas campsite by a local man in what law enforcement officials are calling the largest homicide case in the county’s history.

The campers—at least one of whom was a child—were found dead early Sunday by Anderson County Sheriff’s deputies who were investigating a reported shooting on private camp grounds about 100 miles southeast of Dallas, officials said.

Two bodies were initially found about 7 a.m. Sunday after a sole survivor, identified by the Franklin Sun Journal as Cynthia Johnson, was able to make her way to a main road and call 911.

Four other bodies were pulled from a pond behind a neighboring home that belongs to William Hudson.

Hudson, 33, was arrested and charged with one count of murder but additional charges are expected, according to reports.

He is being held on $2.5 million bond.

Hudson was found at his mother’s property, next door to his home, according to reports.

Information for Hudson’s attorney was not immediately available.

Johnson’s husband, Carl Johnson, their adult daughter Hannah Johnson and her six-year-old son Kade Johnson were killed, the Journal wrote.

Hannah Johnson’s boyfriend, Thomas Kamp and his two oldest children were also found murdered, the Journal reported.

Kamp owned the property the group was staying on in a travel trailer, KYTX wrote.

Hannah Johnson and Kamp lived about 100 miles away from where they were camping, the Journal wrote.

"She moved to Texas a few years ago with her toddler son Kade to be closer to her parents where they retired. She met a great guy and was very happy there," Hannah Johnson's friend, Michael Gilbert, wrote on Facebook.

"She loved camping and was excited to buy her first Airstream camper not long ago. I spoke to her recently and she was very happy.

The suspect is not related to any of the victims, authorities said.

A motive for the murders has not been revealed. Hudson is believed to have acted alone.

The Anderson County Sheriff’s Office believes this is the largest homicide case in the county’s history, KYTX reported.

TX Rangers, Anderson County Sheriff’s Office and Dallas Police Department are assisting in the investigation.
