Mother of 2-month-old killed by babysitter 'asked doctors if he was being abused' days before the horrific incident

Wisconsin woman whose babysitter tried to cover up the death of her two-month-old and returned the child to her pretending he was alive has now opened up about her horrifying ordeal.
Heather Gardner retrieved her lifeless two-month-old son, Benson Xiong, from her 28-year-old babysitter Marissa Tietsort on October 18. She recently spoke to WAOW news about her regret of having left her young son in such horrible care.
Gardner dropped Benson and his older brother off at Tietsort's home, and about two hours later, the baby's mother received a text from Tietsort, in which Tietsort told her that a local news website published a story saying she'd been charged with child abuse and she isn't supposed to have contact with children. Tietsort went on to tell Gardner to not tell anyone she was watching her two sons.
