Over 30 years of retirement, Johnstone would collect as much as $2.54 million, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Johnstone received $53,319 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Johnstone will have already received $108,238 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
