LIMESTONE COUNTY, Ala. (WHNT) — Tuesday marked day six of testimony in the Mason Sisk murder trial.

The first witness called by the state Tuesday was former Limestone County Sheriff Mike Blakely. He is currently serving out a sentence for theft and ethics charges in the Franklin County Jail but was sheriff at the time the shooting happened.

On the night of the shooting, Sisk, who was 14 at the time, spent time alone with Blakely in his truck. Blakely then brought Sisk to the Limestone County Sheriff’s Office.

Blakely testified saying it was clear when Sisk was treated as a witness versus when he was under arrest.

Blakely was questioned regarding the tactics used on Mason during the interrogation. Blakely testified saying he didn’t see it as being manipulative.

Blakely was then excused and the state brought in former Limestone County Investigator Jamie King.

King was recognized as a weapons expert and testified he was present when the gun was found. King also testified that the weapon wasn’t hard to operate for someone who has experience with bb guns.

Jurors also heard from Johnny Morrell, an investigator and forensics investigator who spoke about Sisk’s parents’ cell phones collected from the home.

After a brief recess following the first part of Morrell’s testimony, jurors were shown the full video of Sisk being questioned in an interrogation room by then-Sheriff Blakely and other officials the night of the shooting.

The confession in the video came after an already long line of questioning by former Sheriff Blakely. In the video, Sisk denied killing his family multiple times, while Blakely accused him of lying.

Sisk had signed a Miranda waiver agreeing to answer questions and waiving the right to have an attorney or other adult present.

Shortly after the video finished, court was adjourned for the day.

Sisk is charged with killing five family members in September 2019. His first trial was declared a mistrial after prosecutors informed the court that FBI computer experts had finally unlocked Sisk’s adoptive mother’s phone.

Now 18, Sisk won’t face the death penalty if convicted but faces life in prison without the possibility of parole.

The State continued presenting its case on the fifth day, focusing on Limestone County Sheriff’s Investigator Kristin King’s testimony and bodycam footage from former Sheriff’s Deputy Andrew King.

Other witnesses called by the state include Mason Sisk’s ex-girlfriend, Alabama Department of Forensic Sciences Biology Section Chief Gina Peterson and Brandon Best, a firearms expert from the Department of Forensic Sciences.
