The Ghoul Next Door!

Teen & boyfriend throw pot party after butchering her grandparents.

A HEARTLESS Georgia teenager slit her own grandparents’ throats with the help of her bloodthirsty boyfriend — and then invited pals over to the death house to smoke weed, say cops!

Cassandra Bjorge, 17, and her 19-year-old beau Johnny Rider have been charged with murdering Wendy and Randall Bjorge, both 63, who were also pounded to a pulp!

The young monsters decided to kill Bjorge’s grandparents because they had become “too strict,” investigators say.

Detective Dave Brucz says, the kill-crazy kids put Bjorge’s mother on a “hit list” along with many members of Rider’s family.
