However, the inmate was pronounced dead about 7:33 p.m.
Solano says prison authorities do not suspect foul play but an investigation is under way.
She provided no more details.
Graham is a medium-security prison opened in 1980 that currently houses about 1,800 inmates.
Hillsboro is 65 miles northeast of St. Louis.
