US child rapist executed with drug causing 'torturous pain'
The US state of Tennessee has executed Billy Ray Irick, an inmate convicted of the 1985 rape and murder of seven-year-old Paula Dyer, by injecting a drug that inflicts "torturous pain". Irick was executed after the US Supreme Court denied a final request to stay his execution. The execution came amid a pending legal challenge against the state's lethal injection.
