A 19-year-old student who survived the Parkland school shooting in Florida last year has taken her own life.
Sydney Aiello's mother Cara said her daughter died last weekend.
She suffered a gunshot wound to the head, according to an official at the Broward County medical examiner's office.
Ms Aiello, who recently graduated from Marjory Stoneman Douglas High School, has been described as a vibrant young woman who was focused on her grades and was a joy to be around.
Her mother, of Coconut Creek, Florida, said her daughter was on campus on the day of the 14 February 2018 shooting.
But she was not in the freshman building where ex-student Nikolas Cruz allegedly carried out the gun rampage.
Cara Aiello said that since the attack her daughter struggled with survivor's guilt and was recently diagnosed with post-traumatic stress disorder.
