Witnesses told deputies that East became angry at some of the girls, went into a rage and began breaking doors and windows, News 13 reported.
He then allegedly hip-tossed some of the 14- to 15-year-old girls, breaking some of their noses and possibly the arm of one of the girls, and allegedly kicked his mother and attacked his father, KRQE said.
"We understand he kicked his father twice and stomped him in the head," Valencia County sheriff's Detective Aaron Jones told News 13. "While his dad was down begging for mercy, he evidently stomped him."
East was holding a knife when deputies arrived, but eventually surrendered without doing any further injury, later telling deputies he had wanted them to kill him, according to the KRQE report.
