Probe on nurse widens:

Italian investigators have widened a probe into a nurse suspected of being a serial killer following pressure from relatives of people died at a Tuscan hospital, media reports said Saturday.

Investigators believe 13 patients, all seriously but not terminally ill, died as a result of being given strong doses of the anticoagulant drug Eparina in the town of Piombino — and have not ruled out uncovering other suspicious deaths.

“Prosecutors and health police are extending their investigation” into Fausta Bonino, 56, as well as speaking to family members of other possible victims, public broadcaster Rai said, after the nurse was accused of administering fatal doses of the blood-thinning drug to patients in intensive care between January 2014 and September 2015.

“We never really understood what happened. Now we want to know if that nurse was working the day my father died,” a man known only as Massimo told La Stampa daily about the death of his 77-year-old parent in 2014.

While police have said the arrest potentially averted further deaths, Bonino’s husband Renato Di Biagio insisted she was innocent and denied reports she had been suffering from depression.

“They’ve slung all sorts of mud at us, how is a man who categorically believes in his wife’s innocence supposed to feel?” he repeated in interviews with several newspapers.
