MARSHFIELD, WI (WTAQ) - Prosecutors could file charges Monday against a 20-year-old man suspected of killing the mother of his child.

An autopsy revealed that 18-year-old Maisie McCullough of Marshfield had her neck slashed, and she was stabbed once in the back.

McCullough was found dead late Friday night at the home she shared with the two-year-old boy and his father on Marshfield’s east side.

The man turned himself in Saturday, but police are not saying what evidence may have been found.

Reports said the two parents had agreed recently to end their relationship – and McCullough was planning to move into her own home, and study for a nursing degree.
