On August 22, 2006, Liz Carroll held a press conference asking that whoever may have taken Fiesel return him. She said, "I need help from the public to help my son, Marcus is my son. I know people think foster care is temporary, but please return him to a hospital. [...] Waking up every morning and not having him run to me is very difficult. I am closer than his birth mother to him." Because no witnesses reported seeing Fiesel in the park with Liz Carroll on August 15, and no trace of him was found, police and the public grew suspicious of Liz and David Carroll's claims.
