Over 30 years of retirement, Casey would collect as much as $131,308, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Casey received $2,760 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Casey will have already received $11,547 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
