Man in Phantom of the Opera mask goes on stabbing spree.

This is precisely why I hate musical theater. From the Daily Mail:

A knife attacker wearing a 'Phantom of the Opera' mask stabbed a woman to death and injured another before slitting his own throat, it has been revealed.

The two victims were working at a language school when the assailant stormed in yesterday evening.

A 23-year-old Asian woman died after being knifed in the chest and neck. Her partially clothed body was found at the scene by police who arrived moments after the attack. The second woman was taken to hospital but was later discharged.

The attacker, aged 29, is believed to have turned the knife on himself in an attempted suicide bid. Police said today his condition was stable and officers were waiting to interview him.
