Tamerlan Tsarnayev, the suspected organizer of the Boston Marathon blast, said that he had heard voices but his parents had not sent him for treatment, Boston Globe reports.
Dzhokhar Tsarnayev was bad with studies at the Massachusetts University. He was also dealing marijuana at the campus.
According to journalists, Anzor Tsarnayev, the father, entered the US by lying about persecution in Chechnya. He failed to give any evidence to prove it.
Authors of the investigation say that Tamerlan Tsarnayev was probably visiting Dagestan in 2011 due to the murder of his friend Brendan Messa. One of the brothers was suspected of the murder.
