Live updates: Austin Thompson sentenced to life without possibility of parole for killing 5 people

Psychiatrist for the defense, Dr. George Corvin, said on the stand that he still doesn't know why Austin Thompson carried out the Hedingham mass shooting.

Corvin spoke to Thompson's personality now, and it caused Thompson to start laughing in the courtroom.

"I hate to say this right in front of him, there's a degree of emotional immaturity in him," Corvin said.

The defense also spent some time asking Corvin about what medication Thompson was using at the time to help treat acne.

The psychiatrist said one of the rare side effects could be the inability to recognize their own reality.

Austin Thompson's defense team called his mother, Elise, back to the stand, and she testified for about an hour and a half Tuesday.

Graphic pictures that she took of Thompson after he shot himself in the head were shown in court.

The photos show Thompson hooked up to several tubes, and massive stitches were visible where he shot himself in the center of his forehead.

"I tried to cover my mouth because I started to scream, and I remember that they caught me because my knees just buckled," said Elise Thompson. "The bullet went in his forehead, it went out the upper left side of his skull, and they had to, he did not have a skull for, I want to say, till the following March."
