A teenager who survived the Parkland school shooting in Florida has killed herself while struggling with survivors’ guilt, local media reported Friday. Sydney Aiello, 19, was a student at Marjory Stoneman Douglas last February 14 when a former student opened fire with a semiautomatic weapon, killing 14 students and three staff members. Among the dead were two of Aiello’s best friends, Meadow Pollack and Joaquin Oliver.
