The murder of an innocent young woman who was stabbed to death in her own home in front of a young girl could have been prevented if authorities had acted to deport a violent Jamaican drug dealer seven years before, a judge said.
Lloyd Byfield (48) had pursued a relationship with 26-year-old Leighann Duffy before he smashed his way into her flat and attacked her with a knife and claw hammer on September 1 last year.
After pleading guilty to murder, he was sentenced to life with a minimum term of 26-and-a-half years by Judge Nicholas Cooke who told him he may never be released.
He told Byfield he must have had a "heart of stone" to have killed Ms Duffy in the presence of a young girl who was herself attacked when she tried to intervene.
During the Old Bailey hearing, Judge Cooke also expressed his "unhappiness" at the failure of authorities to deport Byfield after he attacked another woman with a chisel and was jailed for 30 months for burglary in 2005, saying the murder could have been prevented if he had been sent back to Jamaica then.
The court heard Byfield, of no fixed abode, burst into the victim's living room and stabbed her 14 times before she managed to stagger next door clutching a wound to her neck. She died two days later.
