CINCINNATI (AP) — Cincinnati officials plan to make changes to improve operations at the city’s emergency call center, which is under scrutiny after the failed response to a teen who was trapped in a vehicle and died after twice calling 911. Mayor John Cranley, council members and other city officials were touring the center Monday. They say they plan to increase staffing and improve technology and working conditions there. Cincinnati’s 911 system has been plagued with problems and is facing renewed questions following the death of 16-year-old Kyle Plush. He died April 10 after becoming trapped in the back of a minivan in his school parking lot. Police couldn’t locate him. His father found his body nearly six hours after the teen’s first 911 call. Cincinnati police say their investigation continues.
