12 News HD has found that Orange County investigators searched an Orangefield home Friday looking for a .22 caliber handgun that was used to shoot a 6th grade math teacher.
Autopsy results show a single .22 caliber bullet was shot into the back of Staci Lisenby's head, which caused her death.
12 News HD Reporter Liz McKernan discovered that the search warrant for that weapon details some chilling testimony.
Investigators learned that in the week leading up to the shooting, the 14 year-old son of Staci Lisenby told one of his friends he was "tired of how strict his parents were and that he intended on killing them both and then running away."
In a search warrant approved last Thursday, the Orange County District Attorney's office got the OK to comb the Lisenby residence a second time on the 2400 block of Oilla in Orangefield.
The were looking for the .22 caliber pistol that investigators said was used to kill the Orangefield Jr. High School teacher.
The warrant 12 News HD obtained Monday said Lisenby was found bleeding on her kitchen floor.
Her 14 year-old son told investigators the two were home alone in the living room when he heard a shot and saw a man run out the door and into the woods.
The teenager told police the suspect fled through an area soaked with water and mud, but investigators couldn't find any evidence in that mud that would indicate an intruder had fled from the home.
One day after Lisenby died, parents of some of her son's friends came forward with information.
The boy's friends told investigators he had found a .22 caliber revolver in the attic that he kept hidden from his parents.
When a friend asked Lisenby's son about a .22 caliber revolver he practiced shooting the teen said "I got rid of that pistol, it's gone forever."
In a press release issued later Friday, the Orange County Sheriff's office would not confirm who they thought pulled the trigger, saying only that key evidence found on the property points to a 14 year-old juvenile who knew the 6th grade math teacher.
So far, no arrests have been made, but the OCSO confirms the investigation has been handed over to the District Attorney's office.
