Administrative Judge Kevin Dougherty, who tried yesterday's cases, is to hear the cases today of 16 teenagers arrested on March 3 following another flash-mob riot.
Over more than eight hours of testimony yesterday, police officers from the city and SEPTA and a Macy's security officer testified about the damage the mob caused.
Bruce Neil, of Macy's, said that about 4:30 p.m. he saw a large group of teens enter the store from Chestnut Street. Before long, a fight broke out resulting in two glass watch counters and a mannequin being destroyed and shoes and clothing being tossed about, he said.
Cameras inside and outside the department store captured some of the lawlessness, but only one youth was identified through the footage.
"Kids were screaming, yelling and scaring pedestrians at City Hall," Police Officer Louis Pagan told Dougherty.
After police moved the throng farther west to 15th and JFK, he said, "at that point, they actually started to throw snowballs at us."
Dougherty ruled that prosecutor Flores had proven that 10 defendants - all males - were guilty of felony counts of rioting and conspiracy and related misdemeanor charges.
A 15-year-old Gratz High School student who was on probation and who had two previous arrests was adjudicated delinquent and could remain in a state placement facility for up to four years, the judge said.
An 18-year-old Olney High 11th- grader was taken into custody, but the judge deferred sentencing him until he received more information on whether the teen had signed a letter of intent to join the military, as he and his attorney said.
Another 15-year-old Gratz student was adjudicated delinquent and given three years in a placement facility.
Another 15-year-old Gratz student was adjudicated delinquent and taken into custody for an unspecified amount of time.
