A 15-year-old Texas boy has been charged with murdering a neighbor in her hot tub — allegedly telling investigators he wanted to see what it was like to stab someone.

The young teen was arrested nine days after school bus driver Dana Magnuson, 62, was found dead with multiple stab wounds inside the shed behind her Hockley home on July 20, officials told ABC 13.

Investigators believe she was first attacked in her hot tub, with the fight moving to her home and then the shed where she was found.

“There was still blood everywhere — all over,” her son, Tyler Pitney, told Fox 26. “To be honest, I don’t think it’s really hit me yet.”

Once under arrest, the teen suspect told investigators he had wanted to see what it felt like to stab someone, sources told ABC 13.

The suspect was not identified because of his age. But the slain woman’s son said the boy was a neighbor who helped his mom with chores like taking care of her lawn.

“Just nothing out of the ordinary, regular looking kid, looks like he comes from a decent home,” Pitney told the local Fox station.

“She was the most loving person, the kindest, sweetest soul anyone’s ever known, and its… This person took a true angel from this world,” he added. “We hope this kid gets charged as an adult.”

Magnuson was a school bus driver who ran marathons and spoke to her son every day, her grieving son said.

A GoFundMe set up by one of Magnuson’s two sons to cover her funeral expenses had raised over $1,700 by Friday.

“Anyone who knew my mom, knows that she loved everybody and would give the shirt off her back or the shoes off her feet for just about anybody in need-especially her friends and family,” her son wrote on the page.

The teen is currently being held at the Harris County Juvenile Detention Center.
