A law student who stabbed his guardian to death in a frenzied attack is to appeal his murder conviction.

David Quartey, 22, was jailed for life in August 2008 after being found guilty of murdering consultant paediatrician Dr Victoria Anyetei, 54, on the driveway of her Dartford home.

Describing him as a “highly dangerous young man”, the judge recommended he serve a minimum of 15 years for the August 2007 attack of “enormous brutality”.

But Quartey, of Humber Road, Dartford, and son of a High Court judge in Ghana, will seek to have his conviction overturned at London’s Appeal Court on November 13.

Mother-of-one Dr Anyetei was about to leave for work at St Thomas’ Hospital when she was stabbed 56 times as she sat in her car outside her Teynham Road home.

During the month-long trial, Maidstone Crown Court heard that Quartey was under pressure from failing vital college exams for a second time and did not want his family in Ghana to find out.
