The suspect in the 2018 killing of 17 people at a Parkland high school is finally going on trial — but not for the slayings. Jury selection begins Monday on charges Nikolas Cruz attacked a Broward County jail guard nine months after the February 14th, 2018, shootings at Marjory Stoneman Douglas High School. Cruz, a former Stoneman Douglas student, brawled with Sergeant Raymond Beltran after being jailed on charges of killing 14 students and three staff members and wounding 17 others. The 23-year-old faces a possible 15-year sentence if convicted of attempted criminal battery on a law enforcement officer and three lesser charges. No date has been set for the murder trial, which has been delayed by the pandemic and arguments over witnesses and evidence. It may start in the next few months.
