The grandfather of a 21-year-old Wisconsin man accused of kidnapping 13-year-old Jayme Closs and killing her parents during a home invasion says his grandson was "quiet and shy."
Jim Moyer told ABC News on Tuesday that his grandson, Jake Thomas Patterson, is a "nice boy, polite" who often "backed off from crowds."

Moyer says "Computer games were more of a priority than social interaction" for Patterson. The grandfather says Patterson's family is "absolutely heartbroken."
Patterson was charged Monday with two counts of intentional homicide, one count of kidnapping and one count of armed burglary. Prosecutors say more charges could come later.
