Marathon County Circuit Court Judge LaMont Jacobson ruled Friday there was enough evidence to proceed with the case against 28-year-old Marissa Tietsort, of Wausau.
A criminal complaint alleges Tietsort caused the baby’s death in October, then put him in a snowsuit and car seat and returned him to his mother — without telling her the child was dead.
Tietsort is charged with first-degree intentional homicide. She remains in the Marathon County Jail on a $500,000 cash bond.
The state has 30 days to file paperwork for the charges against her.
