HARRISBURG, Pa. (AP) — Pennsylvania's prisons chief is making changes within the drug interdiction unit following the death of a 2-year-old dog who was left in a hot vehicle after a training exercise. Corrections Secretary John Wetzel said Thursday that Totti the dog's handler and his supervisor were reassigned at Rockview State Prison outside State College and a review is underway to determine if discipline is merited. A senior officer with military experience handling dogs is taking over as leader of the drug interdiction unit. Totti died after spending about three hours locked in a car on July 7. He died at a veterinary clinic from a heat-related seizure.
