WAAY 31 is learning more about the 14-year-old suspect accused of killing his whole family.

The Limestone County Sheriff's Office told WAAY 31 John and Mary Sisk were among the adult victims. The suspect is also accused of killing his three siblings.

We know John Sisk, the suspect's father, and his biological mother had not been together for quite some time. The suspect's mother actually died in 2011 in Indiana. WAAY 31 uncovered court documents from 2010, where John Sisk was asking the courts for custody of his son, who is now accused of killing him. The suspect would have been six at the time that this custody battle was playing out.

In the court documents, John Sisk is explaining why he's the better parent fit to raise his child. He says the suspect's mother struggled with drugs and alcohol and hadn't seen her son in some two years. On three separate times, Sisk said in the documents that the police returned the child to him because of the mother's 'condition.' Sisk said he had been the primary caregiver of the child.

Sisk was awarded custody in 2011 because of the mother's death.

WAAY 31 also learned John Sisk himself was facing some criminal charges. In April 2019, he was indicted by a Limestone County grand jury for an armed burglary in February 2019. According to the documents, Sisk and another person went to a man's home with the intent to rob him. The indictment said Sisk then used a pistol to cause harm to the victim.

Sisk was never convicted in the armed burglary case, because it hadn't gone to trial yet.

WAAY 31 also reached out to Morgan County, Indiana, where documents reveal that John Sisk was charged in 1998 when he was 18 years old with sexual misconduct with a minor and invasion of privacy. 

Indiana state law has the definition of sexual misconduct as someone who has intercourse or deviant sexual acts with a minor ages 14 to 16. 

The Indiana documents show that Sisk took a plea deal in 1999 and pleaded guilty to the sexual misconduct charge. It's a Class C felony. The invasion of privacy charge was dropped in the plea deal and Sisk served 180 days in the Morgan County, Indiana Jail. 

Since Sisk pleaded guilty to a felony in Indiana, he could not legally own a gun because he was a convicted felon. Investigators are still working to determine how the 14-year-old suspect got the gun. We know they are checking serial numbers to see if it is stolen.
