A man convicted of shooting his ex-fiancee dead after a campaign of intimidation has been sentenced to a minimum of 30 years in jail.
Mark Dyche has been convicted of Tania Moore's murder
Derbyshire digger driver Mark Dyche, 36, murdered 26-year-old showjumper Tania Moore in March 2004.
He ran her car off the road and shot her in the face, several years after being jilted by her.
He was also found guilty of conspiracy to rob the young equestrian. He had denied all charges.
Judge Mr Justice Bean said on Friday he was a "cold, ruthless and dangerous killer" who had shown no remorse and was branded "loathsome" even by his own defence team.
Nottingham Crown Court heard Dyche, who lived with his mother in Thurvaston Road, had a history of stalking women and had threatened his former wife at knifepoint 10 years earlier.
Miss Moore died almost instantly after the shooting.
She was found lying across both seats with her head against the passenger door.
Outside court, Miss Moore's mother Stella said she believed Dyche should not leave prison until he was dead.
She said: "We have experienced a horrific premeditated murder by Dyche - an evil, cold-blooded psychopath.
Dyche will serve at least 30 years in prison
"Dyche had a gun licence which should have been removed when he assaulted my daughter Tania.
"My daughter Tania died - an innocent life has been lost - but this could have been avoided if the authorities had acted.
"Dyche must leave that prison in a box and no other way."
A memorial fund has been set up in Miss Moore's memory and any money raised will be used to help underprivileged children work with horses.
As well as being an accomplished showjumper, Miss Moore taught many youngsters to ride through her work as an instructor.
She was returning from one of these lessons when she was shot.
Dyche's sentence came after his co-defendant, Jason Bloor, a police informer, was found guilty by the jury of conspiracy to rob Miss Moore.
Bloor was remanded in custody until 26 May when he will be sentenced, along with four other people who have pleaded guilty to various offences in connection with the case.
Miss Moore was beaten by a gang wielding baseball bats and robbed in an attack in June 2003 planned by Dyche.
Mr Justice Bean added: "The failure to bring anyone to justice for the robbery in 2003 despite the apparent tip-offs by Bloor and the failure to act on Tania's report of the many harassing text messages are matters of serious concern."
Colin Colley, a 41-year-old from Stoke-on-Trent, who was later offered £50,000 by Dyche to take the blame for the shooting, pleaded guilty to conspiracy to cause grievous bodily harm to Miss Moore before the trial and gave evidence for the prosecution.
