Adrian Lamo, the former hacker who reported Chelsea Manning to US authorities for leaking hundreds of thousands of classified State Department records, has died at the age of 37, according to a family Facebook post and a report from ZDNet, which cited two of Lamo’s family members and a county coroner.

“With great sadness and a broken heart I have to let know all of Adrian’s friends and acquittances that he is dead,” his father, Mario Lamo, wrote in a Facebook post. “A bright mind and compassionate soul is gone, he was my beloved son.”

It’s not yet known how Lamo died.
