Here’s a chilling, sad, and ridiculous story out of Norfolk, Virginia.

And otherwise well-balanced high school sophomore has pleaded guilty to two counts of second-degree murder after he beat and stabbed both of his parents to death. The reason?

“I just remember getting mad. It’s all from my dad. All this stuff like my dad taking away my iPod and stuff.”

WTKR reports that 16-year-old Vincent Parker waited for his mother to come out of the bathroom, sprayed her with pepper spray, stabbed her in the eye with a knife, and beat her to death with a baseball bat. It was a particularly brutal killing, as Parker’s mother Carol had at least 25 different “smashes and stabs” to her head and neck region.

The brutality doesn’t stop there, however, as Parker waited for his dad to come home, hit him with a crowbar, and then stabbed him as well. According to police, Wayne Parker held on long enough to clue them in on what had just happened.

RT reports that Parker maintained a very active online presence, but never expressed any ill will toward his parents. State psychiatrists who examined the young boy found him to be both intelligent and sane. He’ll be sentenced, as an adult, in September.
