Diane Sawyer's back in Camden on Nightline Friday night (12:35 a.m., ABC), with an update on six of the city's young residents who were featured in what later became her Hidden America series for the network more than 10 years ago.

Among them is Ivan Stevens, who was 4 when ABC News first met him, "homeless and praying for Superman to find him a home," according to the network.

Now Stevens, who recently lost his mother to cancer and was featured last month in an Inquirer and Daily News story involving his summer job as a canoe guide on the Cooper River, is getting ready to start his junior year of high school.

For Sawyer's original report, "Waiting on the World to Change," ABC News spent 18 months with Stevens' family and the families of other young people in the city that was then considered "the most dangerous in America" and contrasting it with nearby Moorestown  for a report that received widespread attention and led viewers to contribute enough money to change the lives of some of the children featured.

Nightline's report notes that Camden, too, has changed, and that while it remains one of the nation's "most dangerous cities… the number of murders is now at its lowest in 25 years."
