A Florida jury on Thursday decided to spare Nikolas Cruz, the gunman who killed 17 people in 2018 at a high school in the city of Parkland, from the death penalty, instead calling for life in prison without possibility of parole.br br 24-year-old Cruz had pleaded guilty last year to premeditated murder at Marjory Stoneman Douglas High School. He used a semi-automatic rifle to kill 14 students and three staff members in one of the deadliest school shootings in American history.
