Over 30 years of retirement, Tyrrell would collect as much as $2.5 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Tyrrell received $52,523 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Tyrrell will have already received $162,344 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
