Over 30 years of retirement, Roberson would collect as much as $4.04 million, according to a projection by Local Government Information Services (LGIS), which publishes Will County Gazette.
The projection assumes Roberson received $84,845 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Roberson will have already received $262,247 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
