Nurse may have killed more than 200 people

BERLIN - German nurse Niels Hoegel, already serving a lengthy term for previous killings, will go on trial before anguished relatives on Tuesday over the murders of around 100 more people - a spree prosecutors say is unprecedented in the postwar period.

The 41-year-old is accused of intentionally administering medical overdoses to patients in his care in order to be able to bring them back to life at the last moment.

He rarely succeeded.
