EL PASO — Authorities say a former West Texas dance teacher who used a hidden camera to tape his victims has pleaded guilty to sexual exploitation of children and distribution of child pornography.
The U.S. attorney's office says 35-year-old Marco Antonio Alferez, who pleaded guilty Tuesday, remains in custody and faces up to 50 years in prison. No sentencing date has been set.
A September 2010 raid of the instructor's home led to seizure of his computer and dozens of videotapes.
Alferez, in some tapes, is seen setting up the camera and instructing children to undress and try on clothes that he provided. Investigators say Alferez had about 150 videos that he produced, including scenes of him having sexual relations with an underage girl.
Alferez taught at five schools in El Paso County.
