A former teacher at Mayfield Senior School in Pasadena pleaded guilty today to possessing child pornography.
The illegal images were found on a computer belonging to 63-year-old David Hassler when authorities searched his home in November 2007, authorities said. He was among about 10,000 of people arrested in nationwide federal investigation into on-line child pornography.
Hassler, who pleaded guilty in federal court in downtown Los Angeles, could be sentenced to up to 10 years in federal prison.
