On July 18, Marjory Stoneman Douglas school shooter Nikolas Cruz underwent the start of a trial that will determine whether he receives life in prison or is put to death.
Back in October, the confessed killer, now 23, pleaded guilty to all 17 murders and 17 counts of attempted murder. Now, the jurors will decide his sentence. The jury must be unanimous for the gunman to receive the death penalty, meaning that if at least one juror votes for life, that will be his sentence.
