Father of six-year-old girl killed in Sandy Hook massacre is found dead at his Connecticut town hall office from apparent suicide

Richman founded and ran the Avielle Foundation - a violence prevention charity - with his wife Jennifer Hensel in the wake of their daughter's death.

The Avielle Foundation was created within months of the tragedy with the goal of reducing violence and to conduct brain research to determine what leads to violence.

For Richman, the work became a full-time pursuit and he gave up his job as a researcher at the pharmaceutical company Boehringer Ingelheim to dedicate himself to the foundation.
