Nikolas Cruz, the Parkland school shooter formally sentenced to life in prison

Nikolas Cruz is sentenced to life in prison without parole. He killed 17 people and wounded 17 others at Marjory Stoneman Douglas

High School. In October, jurors voted to spare him the death penalty. Their decision was met with dismay and disgust by the victims' families.

Victim's loved ones condemn gunman's defense counsel. Jennifer Guttenberg, whose daughter Jaime died in the third-floor hallway

at Stoneman Douglas, admonished Cruz for hiding his expression with a face mask. She began by explaining the rules and restrictions put

upon the victims' families throughout the trial: None could wear colors symbolic of their loved ones, she said, or audibly react to details about their children's murder.

They've done their best to adhere to the rules while enduring the unthinkable - including the defense attorneys' "blatant disrespect."

 A point of contention for the Guttenbergs, as well as for the parents of Scott Beigel and sister of Joaquin Oliver who spoke after
