Melissa says her 3-month-old grandson, Lucas, died in May 2020 of a severe brain injury which the coroner determined to be consistent with shaken baby syndrome. Her son, Steven, says he is currently under investigation in the baby’s death and denies harming his son.

Steven, who adamantly denies hurting his son, admits he was home alone with Lucas for several hours the evening before the baby was hospitalized. Melissa says she doesn’t believe that Steven would be capable of hurting his child and alleges that his girlfriend, Elke, is responsible for the baby’s death, which Elke adamantly denies.

“She seemed relieved, to be honest. Lighter. Happier,” claims Melissa, describing her perceptions of Elke’s behaviors following Lucas’s funeral.
