Ilkeston murder: Four deny killing Michael Moss
A mother, her son and two other men have been accused of murdering a man after the breakdown of a relationship between her and the victim.
Collette Booth, 47, of Mill Street in Ilkeston, and her son Alan Chapman, 27, of Bath Street, Derby, deny murdering father-of-six Mick Moss of Ilkeston.
Jamie Elliott, 27, from Alfreton, and Nathan Hall, 24, from Birchwood Lane in Somercotes, also deny his murder.
Mr Moss died after an assault at his home on 30 January.
Nottingham Crown Court was told the relationship between Ms Booth and Mr Moss "grew sour" and she began to hate him.
It was alleged Mr Hall and Mr Elliott entered Mr Moss's home and beat him in an attack that lasted about 10 minutes.
The prosecution said mobile phone records and CCTV proved the two men had travelled to Mr Moss's home on the night.
Mr Moss, 48, was attacked in the front room of the house where he had been staying and looking after an elderly occupant, who was in hospital at the time of the assault, the court was told.
Mr Chapman, who was a prisoner at HMP Stockton in the North East at the time of the attack, sent a letter to Mr Moss in which he threatened to "send his mate round and beat him up", prosecutor Peter Joyce told the court.
Mr Joyce said Mr Chapman told his mother in a phone call: "I will ring JJ and JJ will beat him, trust me".
JJ was identified by Mr Joyce as defendant Jamie Elliott.
The trial continues.
