Carlos Sotelo was killed Friday night at around 11:30 p.m. while on his skateboard. Police say he was going down a steep hill on Voight Drive when he crashed and was run over by a car. His brother Miguel said it was "the worst moment of my life. I was screaming. I was just on the floor in a ball." Focusing on all the brightness of her son's life, Mabel Sotelo remembers her son for his generosity and kindness. The family has a memorial in their living room full of photos of their most joyous moments with Carlos. “This is when he graduated and I was just playing with him and I put his robe on. I was so happy," Mabel Sotelo said, pointing to one of her favorites.
