Pediatrician Robert P. Dickey quietly practiced for decades in east-of-the-river Washington, serving underserved neighborhoods, most recently from his stately red-brick home in the Penn Branch neighborhood. But Dickey’s sterling reputation was shattered Wednesday when federal agents raided his home, catching him looking at child pornography on his computer shortly before starting to see the 20 patients he had scheduled that day, according to a court affidavit. Peter Hermann reports in The Washington Post that authorities say “there is no indication that any of the 14 images the FBI found on the computer Wednesday morning involved children the doctor had been treating.” Still, the arrest has shocked plenty, including Dickey’s Penn Branch neighbor Yvette Alexander, Ward 7’s D.C. Council member: “If the allegations are true, it just sickens me,” she said. “He’s been there for years. He’s had generations of children. He was very quiet, very professional, it seemed. … Just to think that someone you entrust your children to might have that mind-set.” Dickey is set to appear in federal court today.
