Kacey Adams, of Covert Road and his accomplice Daniel Wallace, of St Mary’s, Barking, were originally given three life sentences with a minimum term of 12 and a half years earlier this year.

But following an appeal by Essex Police, the pair will now have to serve almost double the amount of time before being considered for parole after Lady Justice Sharp, sitting at the Royal Courts of Justice, yesterday increased the minimum term to 23 years.

In addition, a third man, Edward Dooley, 24, of St Edwards Way, Romford, had his 16 year sentence for conspiracy to murder increased to life with a minimum term of 15 years.

The court heard how the trio had been jailed following two separate incidents last year.

In May 2016, a 54-year-old man was shot by Adams and left for dead in Stanford-le-Hope, Essex, after one of his relatives severely injured Dooley in a machete attack eight months previously.

Dooley instructed Adams, 34, to carry out the shooting as a revenge attack, with Wallace, 33, among those recruited to assist.

All three defendants had denied conspiracy to murder but were convicted following a trial at Chelmsford Crown Court.

In a separate case, Wallace and Adams forced their way into a home in Halstead, Kent, and tortured the homeowners – aged 66 and 64 – for two hours until they gave the pair the codes to their safe.

The thugs tied them up, threatened them with a hot iron and a knife and poured boiling water over them before fleeing with cash and jewellery.

In February, both men admitted two counts of aggravated burglary and two counts of grievous bodily harm.

Det Chief Insp Stuart Smith said: “I believe these sentences reflect the seriousness of their crimes and the harm they caused their victims.

“The public as a whole are protected from these three dangerous individuals.

“While we welcome these significant sentences, the victims in these two horrific crimes will suffer the consequences of what happened to them for the rest of their lives and no sentence can reflect the trauma they have endured.”
