He was named in multiple civil lawsuits but has never been criminally charged. After Jeffrey's death in August 2019, Mark publicly questioned the official suicide ruling, hiring his own pathologist Dr. Michael Baden, who found evidence more consistent with homicide. Mark has advocated for further investigation into the circumstances of his brother's death.
