Debra Chambers worried her partner Colin Randall could be freed from jail after killing son

A judge described the crime he committed against his son as “vile and horrible”, but former cop Colin Randall won’t be in jail much longer.

He was sent to jail last year for punching his baby son so hard the 10-week-old’s liver was “pulped”, but former Queensland police officer Colin Randall could be free soon.

The brutal act came the first time the senior constable was left alone with his son Kye in June 2014.

The then 37-year-old Randall had become obsessed with moving to Hervey Bay but a recent transfer request was knocked back by police.

Former cop Colin David Randall punched his baby son.

On the morning he killed his son, Randall’s wife Debra Chambers had gone to the shops with their first child. Randall stayed at home and put Kye in a swing. The court heard Randall leant down and punched Kyle once, leaving him with severe internal injuries from which he never recovered.

“The child went into cardiac arrest because of the trauma,” Crown prosecutor Phil McCarthy said.

Randall was sentenced to nine years in prison last May after pleading guilty to the lesser charge of manslaughter three days before his murder trial was due to start.

While sentencing Randall in Brisbane’s Supreme Court, Justice Peter Davis delivered a scathing assessment of the 41-year-old, saying he had breached his duty to care for his son in the “most horrible and vile way”.

Randall maintained for three-and-a-half years the injuries were caused by CPR he had incorrectly performed, despite being familiar with the technique.

“It beggars belief in circumstances where he was a trained instructor (in CPR),” Mr McCarthy said.

Randall, who was charged with murder in January 2016, was eligible for parole after five years served, meaning he could be out of jail as early as 2021.

The 41-year-old is also appealing his sentence, hoping to walk free earlier than 2021.

Randall’s appeal attempts have left his ex-wife Ms Chambers upset and furious.

“The courts are saying they can’t prove he intended to kill Kye, but in my eyes, if you are going to punch a two-and-a-half-month-old in the stomach really hard, you are going to kill them,” Ms Chambers told A Current Affair.

“He is very manipulative and very evil. I mean, it takes an evil person to do what he did.”

Ms Chambers said she knew something was seriously wrong when Randall called her and said their son wasn’t breathing.

She rushed home and found her baby boy dying.

“I found him on the ground, blue around the face and laying on the ground on the tiles,” Ms Chambers told the program.

Paramedics rushed Kye to hospital and doctors performed CPR for hours, but he was unable to be saved.

The parole board will hear Randall’s appeal on Friday.
