The court heard Murphy, who is a mother and grandmother, and Hinds, who is a former miner, had been a couple for seven years and had had to endure a campaign of vigilante action against them.
The judge was told that masked raiders had broken into Hinds's house, bludgeoned him across the head and stabbed him in the ribs.
Murphy was also stabbed, her barrister told the court, and the pair had to flee from Doncaster to Spain.
Earlier, Iain Hillis, defending Hinds, said his client had worked at the centre since 1997 and said he had always tried to protect more vulnerable staff members from more violent patients. He said Hinds had spent years caring for his patients.
"He was working under very difficult circumstances," Mr Hillis said.
