William Hudson, and a red tractor with blood stains, was located at his mother's home, pictured above, on ACR 2217 In , on adjoining property to the location where the murders occurred.

PALESTINE, Tex. – The six people murdered at an East Texas  campsite were shot to death in two separate incidents,  the Anderson County Sheriff’s arrest affidavit in the case disclosed Wednesday.

The affidavit said William Mitchell Hudson, 33, the accused killer, accompanied four of the victims to surrounding woods on Saturday evening, where he fired multiple shots, according to the only survivor of the massacre, Cynthia Johnson, 73.

The affidavit reported Mrs. Johnson said Hudson then returned to the campsite, where he chased her husband, Carl, and her daughter, Hannah Johnson, into the family’s camper trailer, firing two shots at first and then multiple shots later.

Mrs. Johnson, the affidavit said, was hiding at the campsite from Hudson when he returned to the trailer, remaining out of sight when she heard the final shots. She reported seeing her husband fall onto the steps of the silver camper.

“She hid until she felt it was safe to move from her position,” said the affidavit. “Later she called 911 (at 9:07 a.m. Sunday), and investigators responded to the scene to find Johnson’s daughter and dead inside the travel trailer.”

Sheriff’s deputies found four bodies at mid-day Monday in a pond behind Hudson’s home on property adjacent to the campsite. They were identified as Kade Johnson, 6, son of Hannah Johnson, 35; Thomas Kamp, 45, boyfriend of Hannah, and two of Kamp’s sons – Austin, 21, and Nathan, 24 — who were visiting from California, where they moved with Kamp’s former wife after a divorce.  

Hudson was arrested Monday at his mother’s home and charged with murder. Bond was set at $2.5 million.

The arrest affidavit said Hudson approached the campers Saturday on a tractor, helping them pull a stuck vehicle from the mud. It said he later returned to socialize and drink alcoholic beverages with them.

Sheriff’s deputies said they found a blood-stained tractor on Hudson’s property, and observed what appeared to be blood stains on his person when they approached his mother’s home to arrest him, according to the affidavit.

They also observed dirt that was freshly unearthed to cover up tractor tires on Hudson’s property in the direction of the pond.

The affidavit did not describe any weapons nor did it provide a motive for the carnage. Carina Kamp, the ex-wife of victim Thomas Kamp, speculated that Hudson was angry because his father had sold the campsite property to Kamp.

“My family’s theory is that Mr. Hudson got mad that my husband bought the land and this (the murders) was something he planned on doing,” she told the Palestine Herald-Press in an interview.

Thomas Kamp lived with Hannah Johnson and her son in the Dallas suburb of Midlothian. The Johnson moved to Texas a decade ago when they retired from working at the University of Maine in Farmington. Their daughter was an insurance adjustor in Fort Worth.

Sheriff Greg Taylor described the carnage as “like a war movie.” He said Hudson apparently lost track of Mrs. Johnson, the lone survivor.

“She was able to hide, thank God,” said the sheriff.
