Andres Adams, or "Andy" as his friends like to call him, was supposed to enter the fifth grade at William H. Frazier Elementary School next week, according to his sister Diana Rios.Instead, his family is planning his funeral.Rios said the family will always remember Andy as a special boy who loved Legos and ice cream with marshmallows."The way he looked at life, I guess, it was different, you know, like, you knew he was special," she said.Rios said her brother was visiting Yosemite National Park and after hiking on a trail, decided to cool off in the Merced River.Andy, his stepmother and his 6-year-old half-brother, Jacob, were swept away by a current.The stepmother tried grabbing the two boys, but the water was too strong. Andy's body was found about 150 yards downstream."I guess a current just swept them, she had a hold of them, but I guess, she hit something," said Rios.The stepmother got out alive, but rescue crews have not found Jacob and are continuing to search for him. Posters have been put up all along the park asking for help.Rios said she'll remember her brother as a happy kid who loved people, soccer and ice cream."He loved food; oh my God, he can eat. He can eat for days," said Rios.Meanwhile, Andy's stepmother is still in the hospital with a spine fracture.A memorial service is scheduled for Andy on Wednesday and a burial will take place Thursday in Fallbrook.
