A nurse has been convicted of using insulin to murder two patients at a British hospital in 2011.

Victorino Chua was convicted Monday by a Manchester Crown Court jury that had been deliberating for 11 days.

He was cleared of a third murder.

The nurse was found to have injected insulin into saline bags and ampules while working at the Stepping Hill Hospital in Stockport, 200 miles northwest of London.

Other nurses who were not aware of the tampering then used the bags and ampules, leading to insulin overdoses.

In a letter entered as evidence, the 49-year-old nurse said, "There's a devil in me." He wrote that he was "an angel turned into an evil person."
