Female serial killer stands by pleas A BRITISH female serial killer who admitted to murdering three men will stand by her guilty pleas. The bodies of Lukasz Slaboszewski, 31, Kevin Lee, 48, and John Chapman, 56, were found in ditches in Cambridgeshire, England, in March. Joanna Dennehy, 31, pleaded guilty to the murders at the Old Bailey, but lawyers were granted time to apply to change these pleas after the court heard they were "unexpected." They have now confirmed to the court that no application will be made. After entering her pleas, Dennehy told judge Justice Sweeney: "I've pleaded guilty, and that's that." But her barrister, Nigel Lickley QC, said: "The course of the arraignment is not one we had anticipated." The bodies of the victims were found in March and April. All three had been stabbed. Dennehy also admitted "preventing the lawful and decent burial" of all three murder victims and two charges of attempting to murder two other men.
