With 17 reported casualties, the massacre at Marjory Stoneman Douglas High School in Parkland, Florida, on Wednesday stands as the deadliest school shooting to occur in the U.S. in the past five years. In addition to joining the list of the country’s 10 worst mass shootings, the tragedy is also the 18th school shooting this year.

Nineteen-year-old Nikolas Cruz, a former student once expelled from Douglas High, was taken into custody by law enforcement and now faces 17 counts of premeditated murder. Officials tell AP Cruz legally purchased the AR-15 assault rifle used in the attack about a year ago.

Philadelphia leaders took to social media to weigh in on what has become a disturbing trend.
