Pienta’s grandmother Cheryl told KPIX of her grandson, “He was a good boy, he was a quiet, gentle boy. He didn’t harm anybody. This is so out of character for something like this to happen to him. I don’t understand.”

His aunt said there was nothing they could have done to stop the incident. “He was a great kid,” she said. “He minded his own business, he did good in school. He was one of the sweetest, most lovable, kindest, cutest, just so bashful and compassionate. He e didn’t deserve any of this, nobody saw this coming. '

She added that her nephew’s death was “an absolute tragedy and a loss.”
