Alabama Teen Convicted Of Fatally Shooting Parents, 3 Siblings — Including His 6-Month-Old Brother — While They Slept

A jury in Alabama has found a teenager guilty of murdering five members of his family.

Following seven days of testimony, jurors deliberated for two hours before determining Mason Wayne Sisk, now 17, was guilty, The News Courier reported.

On Labor Day, Sept. 2, 2019, Sisk, who was 14 at the time, fatally shot his family — father John Sisk, 38; stepmother Mary Sisk, 35; brothers Grayson “Kane” Sisk, 6, and Colson Sisk, 6 months; and sister Aurora “Rory” Sisk, 4 — while they slept at their home in Limestone County.

“The important thing is that Mason Sisk will never hurt anyone again,” District Attorney Brian Jones said after the verdict was delivered.

In court documents filed before his trial and obtained by Al.com, Sisk’s defense attorneys claimed their client had “diminished culpability” because he allegedly was the victim of sexual abuse, bullying and he witnessed domestic violence.

Sisk faces up to life in prison without parole when he is sentenced on July 25. He is not eligible for the death penalty since he was a minor at the time of the killings.
