A Sheriff's Department sergeant and a court clerk were injured in a chain reaction incident involving two elevators at the Criminal Justice Center in Philadelphia, reports WPVI.
It happened just before 10:30 Thursday morning in a bank of elevators reserved for employees at the CJC.
There was a failure at the top of one elevator, sending it flying up into a maintenance room and breaching the shaft ceiling, with a sheriff's deputy inside. Debris from that crash hit a second elevator, carrying a court employee.
The 48-year-old Sheriff's Deputy, identified as Sgt. Paul Owens, was taken to Hahnemann University Hospital in critical condition where he underwent surgery after suffering broken bones in his back.
The court clerk who was hurt, Beverly Smith, was treated at the hospital and released.
