Ex-teacher failed to register as sex offender

A former District teacher pleaded guilty Friday to failing to register as a sex offender, the first defendant to be indicted and convicted in D.C. under the Sex Offender Registration and Notification Act. Anthony Ross, 42, a former coach and teacher at H.D. Woodson High School, was convicted in 1999 of sexual abuse for having sex with a 15-year-old District student.

Prosecutors said Ross used a bogus date of birth and false Social Security number to avoid detection. U.S. Marshalls had been searching for him since 2006. Ross was arrested in Ohio in 2010, just days before he was to be married.
