Justice department translated recordings made in Portuguese by man believed to be behind killings

The man accused of killing an MIT professor and two students at Brown University left behind video recordings in which he says he had planned the attack for years, the US Department of Justice said on Tuesday.

The shooter in the 13 and 15 December attacks was a former Brown student and Portuguese national, whom law enforcement found dead in a New Hampshire storage facility days after the shootings.

In damaging intelligence breach, Ames admitted to passing information to Moscow for nearly a decade

Aldrich Ames, the CIA agent who spied for the Soviet Union and Russia in one of the most damaging intelligence breaches in US history, has died in a Maryland prison. He was 84. His death on Monday was confirmed by the Bureau of Prisons.

Ames is best known as an ex-CIA agent who spied on the US on behalf of the Soviet Union. Ames, along with his wife, Rosario Ames, was arrested in February 1994 and pleaded guilty without a trial to espionage and tax evasion. Aldrich was charged with espionage, and his wife with aiding and abetting his activities.
