Simon showed old photos of their family together to Benson, stating Hollister was a good father but struggled with depression. Hollister stopped raping because his libido was lost from anti-depressants. Sharon divorced Hollister and kicked him out when he endangered Simon. When the medication stopped working, Hollister turned to alcohol, then committed suicide by shooting himself with a revolver. (SVU: "Florida")
