RAMONA -- A critically ill Ramona boy who suffered a deadly bacterial infection died Sunday at Rady Children's Hospital in San Diego, a San Diego County medical examiner's investigator said today.

Carlos Don, a 12-year-old sixth-grader at Hanson Lane Elementary School, was diagnosed last month with methicillin-resistant staphylococcus aureus, a skin infection that spreads to the respiratory system.

Carlos was one of 200 students from Hanson and James Dukes elementary schools who attended Camp Cuyamaca the week of Jan. 15, authorities said.

The family said when Carlos returned home Jan. 19 he felt seriously ill with shortness of breath, and he was later rushed to the hospital. Blood drives were held to help him get the O-positive blood Carlos needed as he struggled for life.

The healthy, popular boy who played Pop Warner football, loved to skateboard and was an all-round athlete died at 2:40 a.m. Sunday at the hospital, the medical examiner's investigator said.
