A cuckolded husband went to confront the friend who had a two-year affair with his wife – and ended up dead.

Andrew Jenkins, 54, was angry after being told his wife Louise had been meeting her lover, ex-soldier Jeffrey Mills, twice a week for sex.

A jury at Maidstone Crown Court heard how on the morning of May 17 he armed himself with a knife and drove to Cambridge Crescent in Shepway to confront his rival.

Prosecutor Adam Feest QC said: "The defendant shot and killed Andrew Jenkins with a Glock 2.3 pistol with a single bullet.

"Mr Jenkins had discovered two weeks earlier that Mills had been having an affair with his wife.

"He took it upon himself to go to Mills' flat to confront him about what he had done to his wife."

Mills, 54, has pleaded not guilty to murder and is expected to claim self-defence.

The prosecutor told the jury that Mr Jenkins, from Rochester, was angry and pushed past Mills' wife who had tried to stop him.

"He took one small step into the hallway when he was shot from a very small distance away by Mills."

Mr Jenkins managed to stumble away and threw away the knife before collapsing and died shortly afterwards.

Mr Feest added that the Crown claim that Mills had used disproportionate force in shooting a man he didn't know was armed.

"The two families had known each other for many years and had been close friends," he said.

"For around two years prior to the incident, Mills and Mrs Jenkins had been having an affair. They would meet in hotels once or twice a week for sex."

But in March the affair was exposed when their lover's tryst in a hotel had been seen by a friend.

Mr Jenkins was then told by his wife and began making threats against Mills and his son, the jury heard.

On the day of the shooting, Mrs Mills called 999 and told an operator: "My husband had an affair with this man's wife...and he's just come up here with a knife and threatened to kill my husband.[Come] quickly, he is a nutter this guy."

Body-worn footage made by the first officer on the scene revealed that Mills had unloaded the gun, telling the policeman: "I just did what had to be done."

After his arrest Mills said he had taken threats by his rival seriously and bought three weapons, the illegal Glock and two ball-bearing guns.

Mr Feest said that the victim had died within minutes after the single shot had passed from left to right, hitting him in the chest and damaging vital organs.

Mills admitted firing the single bullet but denied trying to kill Mr Jenkins saying had he intended to he would have aimed for his head. He also admitted three other firearm charges.

The trial continues.
