The McDonald’s Handoff: The Chilling Betrayal and Death of Two-Month-Old Benson

When Heather arrived to pick up her two sons on October 18, 2018, in Wausau, Wisconsin, she believed she was simply ending a normal day. Instead, she was stepping into a nightmare orchestrated by her babysitter, 28-year-old Marissa Tietsort. The investigation that followed would reveal a level of calculated cruelty that shocked the community and seasoned investigators alike.

Earlier that day, tragedy had already struck inside the babysitter’s home. By the time Heather arrived, her two-month-old son, Benson, was already deceased. In a chilling attempt to conceal the crime, Tietsort dressed the infant in his brother’s hat, pulling it down over his eyes to hide his lifeless state, and bundled him into his car seat. She even took the deceased infant to McDonald’s with her own children before the handoff, acting as if nothing was wrong. When Heather arrived, Tietsort met her at the door, refusing to let her inside—a detail that Heather and her sister Jesse later realized was a desperate attempt to hide the reality of what had happened.

The horror unfolded at a local laundromat shortly after the pickup. As Heather tried to remove Benson from his car seat, she discovered he was unresponsive and “freezing cold.” Security cameras captured the sheer panic as Jesse dialed 911, screaming for help while the dispatcher desperately tried to coach them through CPR. Despite their frantic efforts and the arrival of paramedics, Benson could not be saved. It was later determined that the infant had suffered blunt force head injuries, a cause of death that rattled the local police department.

The investigation quickly shifted to Tietsort, who was already known to authorities for previous child abuse allegations. Police noted her “beat” appearance and erratic behavior during the handoff, leading them to believe she was under the influence or in the midst of a psychological breakdown. Furthermore, Benson’s toddler brother was found sweating and lethargic, requiring an emergency ER assessment. As police rushed to Tietsort’s residence, they realized they were dealing with a woman who had essentially handed a mother her dead child and said, “Have a nice night,” before attempting to flee the consequences of her unimaginable actions.
