Kenneth Gardner taught at Broadview Middle School. The school's human resources director said in a published report that the science teacher resigned at the end of February, 5 months after Danbury police launched an investigation into child sexual abuse allegations against him and his wife. He and Lisa Gardner were arrested May 31st following an 8 month long investigation into allegations by a child, who is now an adult.
