Webster has pleaded not guilty by reason of insanity in the shootings, which requires prosecutors to prove that he was sane at the time and knew the difference between right and wrong.
Prince said that Webster, located and arrested with the help of the video Meghan Bigelow took, told detectives he had been losing his mind for years and it seemed like he had observed the shooting rather than being involved in it. A psychiatrist told police Webster, then 23, had been diagnosed with bipolar disorder and was prescribed antipsychotics and antidepressant medication, police have said. According to court documents, Webster said he had recently started taking a new medication that day.
However, Prince said Webster acted purposefully on the day of the shooting, hiding his handgun, which had been in the passenger seat, in a backpack in his trunk after the shooting and trying to kill Gale to cover up his actions as proof that he knew what he was doing.
“The evidence will show the conscious decision-making before, during and after his crime,” said Prince, who adds that Webster completed an errand at Home Depot after the shooting and returned to a worksite to finish a construction job.
As Prince talked about the shooting, Meghan’s husband, Vaughn Bigelow Sr., bowed his head at times or rested his head in his hands.
Webster, wearing dress clothes, sat next to his lawyers, often writing on a yellow legal pad during testimony.
The defence did not provide an opening statement, which they are not required to do, and has not had the opportunity to present any witnesses yet.
