ZDNet reports: His father, Mario, posted a brief tribute to his son in a Facebook group on Friday. "With great sadness and a broken heart I have to let know all of Adrian's friends and acquittances that he is dead. A bright mind and compassionate soul is gone, he was my beloved son," he wrote. The coroner for Sedgwick County, where Lamo lived, confirmed his death, but provided no further details. Circumstances surrounding Lamo's death are not immediately known. A neighbor who found his body said he had been dead for some time.
