The 57-year-old White was in court on Friday to reopen a lawsuit against the Rolesville Police Department over body camera footage she said she never received.
Police said White left the courthouse, got a handgun from her car, came back, and shot Mary Katherine Harris and Jeffrey Whitley, the two attorneys representing the Rolesville Police Department.
According to a newly obtained search warrant, detectives found a Radical Firearms rifle, a Marlin 39A rifle, CDs, flash drives, and notebooks inside her Raleigh home.
Documents also showed that White recently called a medical facility with threats to carry out a shooting.
ABC11 also obtained exclusive audio from inside the courtroom just minutes before last Friday's shooting.
In a recording released to our newsgathering partners at the News and Observer, White can be heard shouting before she left the courtroom.
"I'm going after you. I'm going completely after you all the way up to the top. I promise you that. And I'm going to get her. See ya. So throw it," she's heard saying.

White now claims she cannot remember the events of last Friday.
She was committed to Central Regional Hospital in Butner, where she'll undergo observation and treatment to determine her capacity to proceed forward in the case.
She will return to Wake County when the evaluation has been completed.
White is charged with two counts of attempted first-degree murder.
