Lamo's father, Mario, announced the news Friday on Facebook. "A bright mind and compassionate soul is gone, he was my beloved son", Lamo's father, Mario Lamo, wrote in a Facebook group page.
Kate Flavin, a spokeswoman for Sedgwick County, Kansas, where Lamo lived, and for the county's regional forensic science center, confirmed his death.
Adrian Lamo, a hacker who informed the government about Chelsea Manning's theft of secret documents, has reportedly died. Lamo, who was living in Wichita, Kansas, was 37.
Lamo first gained media attention in the early 2000s for breaking into several high-profile computer networks, including those of The New York Times, Yahoo, and Microsoft, culminating in his 2003 arrest when he eventually turned himself in.More news: Students walk out in East Hartford to protest gun violence

Lamo's cause of death had not yet been released.
Adrian Lamo was called by some the "world's most hated hacker" at the time he turned in whistleblower Chelsea Manning, whose leaks exposed the nature of warfare in Afghanistan and Iraq. He pleaded guilty for the Times hack and was fined and sentenced to six months of home detention.
The Guardian reports Manning contacted Lamo online in 2010 after reading an article about him, and has this quote from Lamo: "Had I done nothing, I would always have been left wondering whether the hundreds of thousands of documents that had been leaked to unknown third parties would end up costing lives, either directly or indirectly". But, Lamo chose to report him and informed the US military of the breach. Her sentence was later commuted by President Barack Obama, and she was released previous year.
Since turning Manning over to the authorities, Lamo had expressed mixed feelings on his actions and, although he described a "lasting regret" in one interview, he stood by his decision. She has since launched a campaign for the U.S. Senate.
