LAS VEGAS -- Tragedy has struck a Las Vegas family again after a deadly ATV accident in Utah.
The Las Vegas Review-Journal reports 16-year-old Christina Portaro, a junior at Faith Lutheran High School, died in the crash Saturday night in Brian Head, Utah.
In March, her brother, Michael Portaro, was gunned down outside the Tenaya Creek Brewery in Las Vegas. A suspect in his death remains in jail.
The Salt Lake Tribune reports Christina Portaro was riding with a parent and friends when her ATV rolled on top of her as they drove up a steep incline in Brian Head.
Witnesses say she was wearing a helmet, but it came off in the accident. She suffered massive head injuries.
She and her family were spending the holiday weekend at their Brian Head condo.
