FOXBORO (CBS/AP) — The man at the center of a murder-suicide in Foxboro last week was a loving father who struggled with post-traumatic stress disorder after serving in Iraq in the 1990s, according to his family.

Police say 49-year-old William Scaccia Jr. shot his 6-year-old son Anthony in the boy’s home last Thursday before killing himself.

Anthony’s mother, Laurie Tolliver, said William Scaccia was “not a monster,” but “one of the greatest guys you could ever meet.”

She says he was an Army veteran with a nursing degree.

Scaccia’s mother, Dianne Usevich, said her son’s PTSD “spiraled out of control” recently, but he was really “a wonderful guy.”
