A former fire department captain in South Lake Tahoe has been indicted by a federal grand jury on child porn charges. Mark Wygant was indicted on six charges. An FBI affidavit says he secretly filmed a child using spy cameras from 2011 into 2012. He’s also accused of obtaining or producing child porn, with images of some children as young as 4. Wygant had been placed on paid administrative leave by the city of South Lake Tahoe following his arrest, but resigned after an investigation into the allegations was completed within days of Wygant’s arrest.
