German nurse 'likely to have killed more patients'

A male nurse sentenced to life in prison for killing two patients with overdoses of heart medication is likely to have killed many more people at two German hospitals, tests suggest.

Oldenburg police chief Johann Kuehme said investigators found residue of a heart drug in 27 of 99 patients from a hospital in nearby Delmenhorst whose bodies were exhumed, the news agency dpa reported.
