Alabama teen Mason Sisk, 18, is sentenced to life in prison for murdering his entire family because he was ‘fed up’: Judge slams him for being ‘draped in unmitigated evil’

An Alabama teenager was sentenced to life in prison for murdering five members of his family in 2019 because he was “fed up” with them.

Mason Sisk, 18, shot his parents and three younger siblings in the head on September 2, 2019, in Elkmont, Alabama.

The teenage killer, who was 14 at the time of his brutal crime, was sentenced Thursday by Limestone County Circuit Judge Chad Wise.

The judge said the crime was “horrific, disturbing and shrouded in absolute evil”.

The life sentence came after Sisk was convicted of four counts of capital murder for the killings of his father John Sisk, 38, his adoptive mother Mary Sisk, 35, and his younger siblings Kane, 6 years old, Rorrie, 4 years old, and Colson, 6 months old. The jury deliberated for less than two hours.

John Sisk, 38, and Mary Sisk, 35, were shot dead alongside their three young children by Mason Sisk who was “fed up” with them.

Sisk murdered his three younger siblings Kane, 6, Rorrie, 4, and Colson, 6 months.

Limestone County Prosecutor Brian CT Jones said, “I’ve prosecuted a lot of people in my career, and I can tell you that out of all those people, only four out of five people scare me and it’s at the top of my list.

Sisk was not eligible for the death penalty because he was under 18 when he murdered his family.

Before sentencing Thursday, members of the deceased family gave victim impact statements in July.

Mary Sisk’s brother, Douglas Prater, said: “On September 1, 2019, I came home with gifts for everyone – including you, Mason. Instead of seeing the happiness on their faces, I had to put these gifts in coffins.

Mary Sisk’s sister Katie told Mason that her nanny didn’t believe he was the killer until the evidence was in front of her face.

Katie said: “How could her first grandson murder his family? She had a heart attack and later died of cardiac arrest. I don’t know if I will ever forgive you, but I am saddened by your loss. The Mason kid I knew died the day you murdered them.

Sisk was 14 years old at the time of his crime, making him ineligible for the death penalty.

The judge wrote that Sisk’s crime was “horrific, disturbing and shrouded in unmitigated evil.”

Matt ‘Gator’ Paddle, who was good friends with John Sisk, described Mason as “a nerdy kid” and said he stayed in his room a lot.

Gator said he felt tension between John and Mary but “didn’t feel any tension between Mason and his family.”

The deputy prosecutor said: “There have been allegations that Mason was abused by John. That may be true, except he took it out on his entire family.

Video footage of Sisk’s confession to the murders showed him admitting to his family’s murders because he was “fed up with all the fighting” in his family.

Some 31 witnesses appeared in court for Sisk’s trial in April, and on the final day of testimony, jurors heard from the prosecution’s investigator witness, Johnny Morrell.

Morrell discussed evidence presented in the case, including Mary Sisk’s cell phone and interviews conducted at the time of the murder when Sisk confessed to the crime.

Sisk’s confession came after a lengthy period of questioning by former Sheriff Mike Blakely.

Lawson live-tweeted the trial in April and said Mason had a “limited reaction” to the jury’s decision, but looked “a little shocked.”

Video of the interview shows Sisk denying killing his family multiple times while Blakely accused him of lying.

The trial was originally held in 2022, but was declared a mistrial after it was discovered that the FBI had ultimately unlocked the cell phone of Sisk’s adoptive mother, Mary Sisk.

At the retrial in April, the judge thanked the jury for dealing with the difficult subject and said it was likely to be changed forever.
