There have been seven full days of testimony in Austin Thompson's sentencing hearing, and the judge is expected to issue his sentence on Friday.
The prosecution and defense made their cases in closing arguments.
"This is a calculated, mature 15-yearold who committed one of the deadliest spree shootings in this state," said Wake County Assistant District Attorney Patrick LaTour. "All of the killings that he does are close up, in-person, and on his path to safety in the woods."
The court will have to decide whether Austin Thompson will be eligible for parole.
Thompson's attorney, Kelly Mann, countered by saying, "There were no red flags in Austin's life. The harm and the pain that Austin has caused is bigger than he could repay in 10 lifetimes."
LaTour added that "the reality is we will probably never know why he did this. He committed violence not once, not twice, not three times, seven times that day. He terrorized an entire community for over an hour."
Mann rejected the notion that the Hedingham mass shooting was a calculated act.
"Austin had no grievance, no cause, no extremism, no preoccupation, no escalating marinating violence. The state wants you to believe that this was very well planned and that he fits the mold of a typical mass shooter," said Mann. "I know it feels safer to put him in that box and to say he's just like everybody else who commits mass shooting. But that is not the truth."
LaTour stated that "In the blink of an eye, everything changed for those people and for the people that they left behind."
Court resumes at 9:30 a.m. Friday.
