Hamilton Fire Chief Mark Mercer said the department was informed of Parker’s death this week.
Parker and Tucker, of Richmond, Ky., were charged with arson and murder in the fire at Parker’s Pater Avenue home that killed Wolterman on Dec. 28, 2015.
Both men denied any involvement in the deadly fire and testified in their own defense.
Tucker admitted to being in Hamilton during the early-morning hours when the fire occurred but said he came to get pain pills from one of Parker’s daughters and then “peddle” them in Hamilton to make money. He also admitted to lying to police when they first questioned him about his whereabouts that day by saying he was in Richmond, Ky.
Parker testified he moved items from his house to his garage to make room for a family gathering, not to spare them from the fire as the prosecution argued.
During trial, now-retired Assistant Butler County Prosecutor David Kash told the jury they could make inferences from text messages and testimony to conclude Parker and Tucker were guilty of murder and arson.

He meticulously went over social media messages, phone records and even a Hamilton police license plate reader that caught the image of the car that a Hamilton woman used to drive Tucker to the city on the morning of the fire.
“Clearly this is a case of circumstantial evidence,” Kash said, telling the jury to “take facts you know and make reasonable inference,”
Kash told the jury that the state is not arguing Parker and Tucker purposely killed Wolterman, but rather conspired to commit arson that resulted in Wolterman’s death.
“If someone acts in partnership with the person who actually committed the crime, he is just as guilty,” Kash said.
Parker was in Las Vegas celebrating his 45th wedding anniversary at the time of the fire.
Kash said a phone call placed to Parker from Richmond, Ky., on Dec. 20 marked when the arson fire was planned. He also pointed to a text message Tucker sent to a girlfriend at 3:30 a.m. on Dec. 28, 2015, saying, “done with the job.”
“The data starts to tighten the noose,” Kash told the jury.
Butler County Prosecutor Michael Gmoser pointed to what he called a “silver bullet” during final closing arguments — a call placed from a phone registered to Tucker’s Kentucky girlfriend to Parker’s house on Dec. 27, 2015.
Parker previously testified he had not talked to Tucker in more than one year before the fire.
“That is the call from Tucker checking in to find out if the deal is still on,” Gmoser said.
