COLUMBUS, OHIO ? In the year before last week’s fatal elevator accident at Ohio State University, service technicians received 22 reports of passengers trapped inside stuck elevators in four high-rise dormitories, according to reports released Thursday by the university.

Seven of those reports came from Stradley Hall, where freshman Andrew Polakowski, 18, suffocated Oct. 20 when he was pinned after trying to leave an elevator stuck between floors.

Four of those reports came from the elevator Polakowski was trying to exit. In three of those, the problem was blamed on overcrowding or passengers jumping inside the elevator; the reports don’t distinguish between the two.

The reports are histories of service requests from October 2005 to September and were compiled by Otis Elevator Co. According to the reports, all the problems were fixed.

Fire officials said the elevator exceeded its 2,500-pound weight capacity by as much as 1,100 pounds when 24 people crowded onto it last week.
