The confession of a Mount Vernon man who pleaded guilty last month to the slayings of three people and kidnapping a teenage girl was made public on Monday.
Matthew Hoffman promised to tell authorities every detail about how and he why committed the crimes, 10TV News reported.
Prosecutors told Hoffman that they would not seek the death penalty if he led them to the bodies of Tina Herrmann, 32; her son, Kody Maynard, 11; and family friend, Stephanie Sprang, 41.
The slayings occurred on Nov. 10 at Herrmann's King Beach Drive home.
Hoffman discussed how he broke inside Herrmann's King Beach Drive home on Nov. 10 and killed Herrmann and Sprang. Hoffman said that he killed them in a panic, as well as Maynard, when he came home from school.
"At this time, I was in a total state of shock," Hoffman said. "I wandered around (the) house, slowly coming to realization of what I had done and how bad it was. "During this time, I killed (Herrmann's) dog because it would not stop barking."
The three bodies were found on Nov. 18 inside a hollow tree at the Kokosing Nature Preserve near Fredericktown in rural Knox County. The remains had been placed in trash bags that Hoffman purchased from a Walmart in Mount Vernon.
The Columbus Dispatch and 10TV obtained store surveillance video on Monday that showed Hoffman walking through the store and selecting items from shelves.
Shortly after the slayings, Hoffman said that he drove to nearby Gambier, where he went to collect gas cans from his vehicle and use them to burn down Herrmann's house.
According to Hoffman, a sheriff's deputy almost immediately pulled up and asked for his driver's license and reason for being there. At that point, Hoffman said that he could not burn down Herrmann's house and returned to his home where he built a campfire outside his house, drank a bottle of wine and burned his shoes.
The bulk of the confession detailed the four days he spent with the 13-year-old girl who he kidnapped. It explained how he let her play Wii video games, how they watched Iron Man movies together, how he cooked her hamburgers and promised her that she would be home by Christmas.
When investigators broke down his door, they found the girl bound on a bed made of tree leaves and blankets in a corner of the home's basement. Hoffman went into great detail about how he chose the girl's home at random to burglarize.
"I did not enter the house to kill those people," Hoffman said. "I did not know a single one of them. I did not know their names and I did not know who all lived at the house. I chose the house to break into because there (were) not any close neighbors and I noticed the garage door was ajar."
On Jan. 6, Hoffman pleaded guilty to all charges against him and was sentenced to life in prison with no possibility of parole.
He faced a total of 10 counts, including aggravated murder, gross abuse of a corpse, burglary, kidnapping and raping the teenage girl.
