EL PASO-- Ex-Irvin High School teacher Marco Alferez has been sentenced to 50-years in prison for child porn-- the maximum sentence.
The former El Paso teacher admitted to secretly videotaping hundreds of students to create his personal child porn collection.
In August, Marco Alferez admitted to making over 150 porn tapes of his students while he was teaching at five different area schools.
He told investigators he placed a hidden camera in a dressing room, before order kids to get completely nude while they tried on different outfits.
Court documents show that in all, 393 of Alferez's students were victimized.
Today, one of those victims and her mother testified, describing the severe psychological trauma they've had to endure because of Alferez's actions.
The victim's mother said the 50-year sentence was a relief.
