To pay tribute, Alex’s hockey teammates wore stickers on their helmets at their games last week.

Alex succumbed to his injuries from the crash and his sister, Charlotte, is still in the hospital.

The siblings, who attended Somerset Academy Losee, were struck while they were coming home from school on Valentine’s Day. According to North Las Vegas Police, they were in the crosswalk at Lone Mountain and Losee Road when they were hit.

The driver, 47-year-old Mark Kline, faces numerous charges, including vehicular manslaughter. Kline lived on the same street as the children and their family.
