A father who inflicted a frenzy of punches to kill his “undernourished” 11-year-old son will serve a minimum of 21 years and a half years behind bars.
Michael Harrison, who waited almost four hours to call 999 after the attack, pleaded guilty last month to the murder of Mikey Harrison - who died in hospital from his injuries.
He was jailed for life at Derby Crown Court on Thursday in a two-hour sentencing.
The court heard the 41-year-old father repeatedly punched Mikey, at his home on the morning of June 18 last year. Mikey weighed 3st 11lb, well below the 5st 5lb average for an 11-year-old.
The force of Harrison’s punches caused a fatal laceration to his son’s liver but after the attack he drove to Heanor’s Shipley Country Park and phoned the ambulance service from his van with Mikey. He falsely claimed Mikey – who could have been saved by prompt treatment – had fallen from a tree.
Passing sentence at Derby Crown Court, Judge Shaun Smith KC told Harrison: “At 18 minutes past one on Saturday June 18 you embarked upon a charade solely intended to protect yourself.
“That was because you had attacked your 11-year-old son Mikey. You hit and punched him many times. At least one of those blows was so hard it lacerated his liver.
“Rather than face up to what you had done, you made a call to the ambulance service to report that Mikey had fallen out of a tree.
“What you did that morning ended the life of a little boy and emptied the lives of many others.”
The judge added that what happened during the assault was a result of Harrison “going crazy” as he damaged furniture and caused multiple blunt force injuries to Mikey.
Opening the case against Harrison, prosecutor Peter Joyce KC told the court: “At 1.20pm on Saturday June 18 this defendant, Michael Harrison, made an emergency 999 call to the East Midlands Ambulance Service, to report that his son had fallen out of a tree in Shipley Park, Heanor.
“He told the emergency services the number of his vehicle and where he and Mikey could be found.”
Mr Joyce said ambulance service staff then arrived to find Mikey struggling for breath, but he went into cardiac arrest and was taken to hospital in Nottingham, where he was pronounced dead at 2.39pm.
The prosecutor said of the victim: “He was 11 years old when he died and he weighed three stone, 11lbs.
“The defendant was spoken to that day by the police as a witness in relation to what was then described as the accidental death of his son.”
The prosecutor added: “His first account was that he had been in Shipley Country Park when Mikey had fallen from a tree.”
But inquiries established that “this entire account was a fiction made up by the defendant to cover up the fact that he himself had fatally injured his son”, Mr Joyce continued.
Following the assault, the court heard, Harrison stripped the Heanor property where he and Mikey had been living “of almost every item that you would expect to find in a home”.
Mr Joyce alleged that Harrison had also cleaned the scene of the attack to remove any prospect of any evidence being found in relation to what he had done to Mikey.
The 999 call took place almost four hours after the attack took place, Mr Joyce said, adding: “In common parlance he (Mikey) had received many blows to many areas of his body.”
In the opinion of an expert who had studied the evidence, Mikey may well have been saved with prompt and appropriate medical treatment, the court heard.
Offering mitigation, defence barrister Vanessa Marshall KC said Harrison would have to bear the “awful, tragic, unforgivable” death of his son for the rest of his life.
Submitting that Mikey’s death was the result of an “isolated outburst of gratuitous violence”, Ms Marshall claimed Harrison had cleared out the property amid safety concerns, having been kidnapped and stabbed by a gang in 2006.
After he was sentenced, Harrison, wearing a white T-shirt with “FAMILY” printed on the front, gestured towards members of the media and said: “I will always love my family no matter what you lot say. Put whatever version you like.”
