MARSHFIELD, Wis (WSAU) A Wood County man who's accused of trying to hire a hit-man entered a 'not guilty' plea on Monday.

Gabriel Campos is already charged with killing his estranged girlfriend Maisie McCollough. The new charges claim that he offered money, his car, and a riffle to a cell-mate at the Wood County jail to kill her new boyfriend.

The original charge dates back to September when McCollough was found stabbed to death in a bathtub. Campos and his 2-year-old son were found in a nearby motel. Police say they recovered the murder weapon in his car, and found blood in the vehicle and on his legs. The case is scheduled for trial in June.
