"This is a guy we want to slow down if not stop completely," Prosecutor Mike Allen told the Cincinnati Post.
Brock also now is wearing something besides a prison uniform: the title of Hamilton County's biggest deadbeat dad.
Common Pleas Court Judge Thomas Crush sentenced Brock for nonsupport of six children.
There are five other nonsupport cases pending in the system against Brock.
In all, eight women say Brock isn't paying child support for 10 children he fathered. Because one child is included in both sets of nonsupport cases, there are 11 cases involving Brock's 10 children, prosecutors say.
"He's a drain on the system," Allen said of Brock. "He's a burden on the taxpayers."
