A District of Columbia man accused of assault in March, but released from jail due to lack of evidence last week, may have been a victim of his past — he was picked out of a crowd by the victim who recognized him from the sex offender list, a spokesman for the U.S. Attorney’s office said.

On March 3, James Blackmon, 46, was walking past police officers as they interviewed a nanny who had been brutally assaulted in a South Carolina Avenue home in Southeast, when the nanny pointed him out as her attacker, court records show.
