Eddie Mentgen

A man being questioned in a Spring Valley murder showed up in a Wisconsin courtroom Monday afternoon.

Thirty-seven-year-old Eddie Mentgen Jr. of Spring Valley waived the right to an extradition hearing.  That paves the way for him to be sent back to the Illinois Valley. 

As of now Mentgen according to Spring Valley Police is charged with violating parole.  However his girlfriend, 28-year-old Marissa Roberts was found dead in his apartment on Friday.  Investigators say she was murdered.

Mentgen has been detained in Wisconsin since he was arrested by state police early Saturday morning.
