A list has been compiled of ten notorious killers of Waltham Forest in the last 50 years.
Some of the unspeakable crimes have left a stain on many communities with special services commemorating the victims' still taking place today.
The crimes listed were either committed by residents of Waltham Forest or were carried out in the borough, or both.
The majority of them are stil alive today and locked away from society.
1. Cop killer Nicholas Vernage is possibly one of the most notorious serial killers of the 20th century.
During the month of November 1991, he stabbed to death three people including Chingford policeman Sergeant Alan King, Vernage's 21 year-old girlfriend Lorna Bogle, and cab driver Javaid Iqbal.
Sgt King died on duty on November 29 1991 when he confronted Vernage during a burglary in Higham Hill Road, Walthamstow. He was sentenced in 1992 to five life sentences.
2. Schizophrenic cannibal Peter Bryan was jailed for the rest of his natural living life at the age of 34 in 2005 after pleading guilty to two counts of manslaughter on the grounds of diminished responsibility.
In 1993, he beat 20-year-old shop worker Nisha Sheth to death in her family’s store in Chelsea.
By 2001, he was freed following a health tribunal but three years later, he then went on to kill his friend Brian Cherry at his Walthamstow flat.
After killing Mr Cherry, he sawed off his arms and left leg and was found by police cooking part of his victim’s brain.
While on remand, he stangled fellow patient Richard Loudwell at Broadmoor special hospital in 2004.
3. Richard Fielding of Walthamstow was an arsonist killer responsible for wiping out four generations within the same family.
On March 6 1999, Fielding set alight to the family home of his school friend Lee Day in Bellamy Road, Chingford, after holding a grudge against Mr Day after accusing him of ruining his chances of a successful career.

In 1966, he was jailed for a minimum of 30 years for the Shepherd Bush murders in which three police officers were shot dead, two by him and the third by his accomplice.
Roberts feared officers approaching his van would find a stock of firearms he had in possession so he opened fire on the officers.
