Details have emerged of the long history of violence of a man who is beginning a life sentence in jail for murdering a friend over a drug debt.

Theodore Lynch, 41, was told he will serve at least 22 years before he can be considered for parole after being sentenced at Norwich Crown Court earlier this week.

The day before, a jury took less than three hours to find him guilty of his murder of 63-year-old Leslie Smith in 2021 following a violent row at his flat in Suffolk Square over the purchase of drugs.

He was convicted of wounding with intent after stabbing her in the shoulder with a 10 inch knife he had hidden under a pillow after becoming furious his attempts to rekindle their relationship were thwarted.

That was just one of a string of 20 previous violent convictions, many involving weapons including knives.

Judge Alice Robinson said he had an “entrenched pattern of violent behaviour” going back to 2003.

In 2013, then aged 30, he was jailed for three-and-a-half years for wounding and actual bodily harm after he threw a glass object at his former partner causing a gash to her forehead that left her with permanent scarring.

Two years before that he had been sentenced to two-and-a-half years in prison for possession of heroin and crack cocaine.

Detective Chief Inspector Chris Burgess, who investigated the murder, said he was “a very dangerous man”.

“The jury’s decision to convict him of murder will ensure he is kept behind bars for a considerable amount of time, making the streets of Norwich a safer place,” he added.
