A MURDERER who stabbed his neighbour 20 times has been killed by another prisoner in jail, it is understood. John Mansfield was jailed in 2007 for the brutal attack on his neighbour Ann Alfanso, 63. On Sunday, Mansfield was attacked by another prisoner and died despite the efforts of prison staff, The Daily Telegraph reports. A Ministry of Justice spokesman said: “Police are investigating the death of prisoner John Mansfield at HMP Whitemoor on Sunday, April 13. It would be inappropriate to comment further at this time.”Mansfield had 75 prior convictions and was serving a life sentence for the brutal attack on Ann Alfanso.
