Rage Against The Machine guitarist Tom Morello wrote a recent tweet about his old time friend Jeremy Richman, who has died of an apparent suicide.

Unfortunately, the body of Jeremy Richman (49) was found in his office building Monday morning. His was also died in the Sandy Hook massacre in 2012.

Elizabeth Williamson:

“A few reflections from our reporting on the death of Jeremy Richman, Sandy Hook dad who turned his loss into a foundation fostering brain science as a means for understanding violence.”

Tom Morello:

“I knew him. Kind man. Played catch with him backstage at a Prophets Of Rage show. To lose a child and then to be harassed by gun lobby conspiracy theorists claiming your child never died is so so sad and horrible. Rest In Peace now Jeremy.
