Mason Sisk: Shock twist in case of teen who gunned down family after discovering his mom was his stepmom
ELKMONT, ALABAMA: Alabama teen Mason Wayne Sisk, who allegedly murdered five of his family members in 2019, tried to poison his stepmother with peanut butter before he went ahead with the cold-blooded killings, says new court documents. Sisk had reportedly found out his mother was not his biological mother prior to the slayings.
The documents say Mason, who was 14 at the time of the killings, tried to poison his stepmother Mary Sisk, a special education teacher at Mountain Gap Elementary in Huntsville, with peanut butter as he knew she had a severe peanut allergy. However, reports by NY Post suggests that it is not known if the stepmother drank the coffee or suffered an allergic reaction before the teen gunned her down, along with his father, John Sisk, and three siblings in September 2019.
WHNT reports that the discovery filing also alleges Mason threatened his father and stepmother, and was forceful with his siblings, who have been identified as six-year-old Grayson, five-year-old Aurora and six-month-old Colson, at the time of the killing at home. It also stated that he had “anger control” issues with his brother. It was further added by the prosecutors that Mason stole two rings from his stepmother and gave them away; he also stole a gun from his grandmother’s house.
Who is Mason Wayne Sisk?
Now 16-year-old Mason, whose trial began in November 2021, was 14 when he allegedly shot the family members in their shared home in the 25000 block of Ridge Road in Elkmont. The Limestone County Sheriff's Office said Mason called 911 around 11 pm to report the gunfire at his home and later confessed that it was him who fired the gun. The gun used in the homicides was illegal and was recovered the morning after the killings when Mason led officers to the place where he dumped the weapon.
In November 2020, the Limestone County Sheriff's Office announced that Mason will face adult charges of capital murder. In February 2021, the teen was charged on four counts of capital murder, one for each of his siblings and another for his father and stepmother. The five victims ranged in the age from 6 months to 38 years.

A Limestone County School District spokeswoman confirmed the teen attended Elkmont High School. However, as per WHNT, records show the father, John, pleaded guilty to a felony charge of sexual misconduct with a minor in Indiana in 1999, and it is illegal for a convicted felon to possess a gun. A pretrial conference for the case is expected to be held on August 12.
