Over 30 years of retirement, Johnson would collect as much as $770,396, according to a projection by Local Government Information Services (LGIS), which publishes Galesburg Reporter.
The projection assumes Johnson received $16,193 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Johnson will have already received $67,745 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
