University massacre suspect 'troubled'

The gunman suspected of carrying out the Virginia Tech massacre that left 33 people, including himself, dead was identified today as an English major whose creative writing was so disturbing that he was referred to the school’s counselling service.

Police and university officials offered no clues to 23-year-old Cho Seung-Hui’s motive in the massacre, the deadliest shooting rampage in modern US history.
