Nine bones in his face were broken, 15 ribs fractured, a lung punctured, his heart bruised and he had two superficial stab wounds to his arm, a judge heard Monday.
The 68-year-man was assaulted on July 4, 2017, outside a cabin on property where he resided in the town of Spanish, east of Sault Ste. Marie.
Chapman's attacker was a man more than 40 years younger than him — a friend he drank with and reportedly got along well with "for the most part."
There was no particular motivation for Jonathon Jobin's actions, one of the Crown prosecutors told Superior Court Justice Michael Varpio.
Chapman was killed during "a stupid, drunk, immature argument most people would have walked away from," David Didiodato said.
Jobin, 28, was sentenced to eight years in a federal penitentiary for manslaughter — a charge he pleaded guilty to last month.
He had been charged with second-degree murder.
When Varpio imposed the sentence — the result of a plea bargain worked out by the Crown and defence — the judge called the killing senseless.
He pointed to "the severity of the attack" and "the level of the brutality," telling Jobin "you killed a friend, someone you ostensibly looked up to."
With the credit Jobin received for his pre-sentence custody, he will be incarcerated for a further five years, three months, and 20 days.
On Monday, Jobin pleaded guilty to participating in a riot for the part he played in a violent and fiery Jan. 29 disturbance that caused $100,000 damage to the Algoma Treatment and Remand Centre.
He received a 12-month jail term, which will be served concurrently to the manslaughter sentence.
Assistant Crown attorney David Kirk outlined to the court what had occurred in the hours before and after Chapman's death.
Pops was among a group of people who had moved to Spanish from central Ontario, and resided in apartment units in a converted hotel, he said.
Chapman and Jobin each lived in cabins at the rear of the property located at 141 Front St
On July 3, the pair walked down from their cabins to the LCBO store, where the older man went inside while Jobin waited nearby.
Chapman bought a 40-ounce bottle of whiskey and 24 cans of Budweiser beer, which he put inside a red cooler.
His purchases were caught on a security camera at 5:45 p.m, Kirk said.
The men then went to Chapman's place where they were joined by three other people and drank during what most described as a "fairly unremarkable evening."
Between 8:30 and 10 p.m., two people stopped by to pick up one of the individuals to take her to Barrie.
Everyone left, and Jobin and Pops continued consuming alcohol.
Kirk said Jobin became confrontational. Chapman called a friend, which cell phone records show occurred two minutes before 1 a.m.
Pops indicated Jobin was aggressive, calling him out to fight, and then had gone for a walk to cool off.
The friend told Chapman to tell Jobin to call him back "so he could calm him down."
At that time, a video from the area of the Spanish Inn showed Jobin walking by the building, entering the vestibule of a restaurant where he stayed for about 10 minutes. He then headed back towards 141 Front St.
When Pops never called back his friend, the man tried to reach him at 3:45 a.m.
The friend contacted another man, who along with his girlfriend, went to check on Chapman.
They observed the body of a deceased male outside the unit, with a red cooler and beer cans nearby.
The couple "couldn't tell who it was because of the blood and the position of the body — face down," Kirk said.
When they knocked on the door of Chapman's residence to check on him, the door was locked and they could hear someone yelling inside.
Jobin answered the door. He had just got out of the shower, was wrapped in a towel and had scratches on his ams and chest.
"He became agitated when asked about the deceased male," Kirk told the court. "He said 'I'm not going to jail. I'm not going down for murder.'"
They left and a number of people later went to Chapman's cabin to remove a bag of marijuana stored there.
The accused later returned, stayed there for about an hour, and then left at about 8:30 a.m.
Jobin was carrying a box and a bag, which he stored in the garage of another person's residence.
At 12:10 p.m., the Ontario Provincial Police received the report of a body.
Kirk said Jobin spent a few days at the other residence, where he burned some items, including a cell phone, in a wood stove.
Police seized a box and a plastic bag, which contained a screw driver, two beer cans and personal papers belonging to both men, from the garage.
The burnt cell phone also was recovered.
Jobin was arrested. He initially told police "all was good" with Pops, that he had taken a shower after his walk, and went to another unit to sleep.
He later "indicated he couldn't remember anything. He was too intoxicated," Kirk said.
DNA played a role in what the Crown called a circumstantial case.
Forensic analysis of blood on a beer can connected it to Chapman, while blood on another can was from two contributors — the victim and the accused.
Defence lawyer Daniel Brodsky said "whatever happened escalated out of control quickly."
A lot of the facts aren't known and the evidence is circumstantial, he said, calling it "an alcohol-fueled altercation between friends that escalated and here we are today."
He described his client as a high school graduate, who has nearly always been employed, and has a good relationship with his family, who were "shocked" about what occurred.
Jobin had broken up with his girlfriend, lost his job, got involved with this group of people and came up to Spanish, the Toronto lawyer said.
Jobin had no criminal record, and within two years he is charged with a drug trafficking and murder, Brodsky said.
"This paints a picture of a train going down the track that gets derailed," he argued.
There are good prospects for Jobin's rehabilitation, and he is taking responsibility for what occurred, Brodsky said.
The Crown read a victim impact statement from a woman who described Chapman as "one of a kind," one of the most loving and "most supportive men in my life."
He was a friend, "a go-to person when I needed someone to talk to," she wrote. "His door was always open for all of us who knew him."
The woman said she had a miscarriage from the stress of his death. As the case dragged on she became addicted to drugs and alcohol, and is involved in mental wellness counselling.
"We all need to learn to accept the fact that he is no longer with us," Chapman's friend said. "The only way is to put him to rest."
The court heard Jobin had no prior criminal record, but was on bail for a drug trafficking offence when he was charged in Chapman's death.
He later pleaded guilty to the offence and was sentenced to 30 days custody.
Varpio noted Jobin is a young man with virtually no record, but said he wouldn't describe trafficking and participating in a riot as insignificant contraventions of the law.
A plea of guilt is often seen as remorse and accepting responsibility, the judge said.
"You stepped up and admitted killing George Chapman."
