LANSING, Mich. (AP) -- A new report says unless policymakers reduce the inmate population, Michigan's $2 billion prison system will cost another $500 million in four years.
The Citizens Research Council of Michigan projects the 50,200-inmate population will expand by 5,800 in that time.
The Detroit News says the report was unveiled Friday at a meeting of about 100 prison experts discussing ways to reduce spending while protecting residents.
The state closed two prisons and a reception center last year to save money.
Michigan is trying to speed up the parole process for about 3,500 inmates who were convicted of nonviolent, nonsexual offenses, or who are seriously ill.
