He was recently honored by the Down Syndrome Association of Atlanta (DSAA) for dedication to his work at an Atlanta-area McDonald’s, where he had been employed for nearly three decades.

On the page, Campbell is described as "a boy scout, church acolyte, community volunteer, McDonald's employee, loving son, grandson, brother, uncle and friend. He was so special in so many ways to so many people."

Since 1983, the life expectancy for people with Down syndrome has increased by 35 years, from 25 to 60, DSAA says. There are 400,000 people in the U.S. with Down syndrome, according to its website.
