Granny Beater Kurt CassBradenton, Florida — Deputies say a 16-year-old has been arrested for beating his grandmother with a two-by-four for refusing to give him $100 for beer.

Charged is Kurt Cass of Hammock Drive, Bradenton.

Investigators say Cass went into his 60-year-old grandmother’s bedroom Thursday and asked her for $100 for beer. When she refused, he allegedly placed a razor blade on her throat and demanded she take him to the bank to get the money, deputies said.

“When the victim arrived back home she locked all of the doors,” deputies reported. “The defendant arrived back home and kicked the front door in.

“Once inside the defendant grabbed a two foot 2×4 piece of wood and hit the victim numerous times on the back. The defendant then grabbed a three foot piece of 3 inch PVC pipe and hit the victim on her head, back, and legs numerous times. The defendant’s case worker arrived on scene and was able to hold him until law enforcement arrived.”

Deputies said Cass has made comments in the past to his grandmother that she should kill his entire family.

Cass was charged with domestic aggravated assault, two counts of domestic aggravated battery, attempted robbery, and kidnapping.

The grandmother has had legal guardianship of Cass and his little brother since 1994.

Authorities tell us today that Cass came from a troubled family. His mother is in prison on cocaine possession and sale charges, and his father is serving a 15-year prison sentence for manslaughter after choking a prostitute to death in 2002.
