Over 30 years of retirement, Johnson would collect as much as $837,135, according to a projection by Local Government Information Services (LGIS), which publishes Rock Island Today.
The projection assumes Johnson received $17,595 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Johnson will have already received $35,718 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
