When a 30-year-old San Diego father took his family to a local cemetery and told them his dead grandmother had instructed him to sacrifice the 8-year-old boy, he allegedly got as far as using a piece of broken glass to slash open his son's forearms and his own, NBC San Diego reports.

"I think sometimes people are put in places. And honestly, we were at the right place at the right time," Granberry said.
