One of the men accused of murdering Stephen Lawrence was at home making toast at the time of the killing, his mother has told a jury.
Pauline Dobson insisted that she had seen her son Gary in the kitchen of the family home in Eltham, south-east London, at around 10.30pm on April 22 1993.
She said: "At half past 10 I went into the kitchen to make a cup of tea... Gary came down to make toast at 10.30pm, twenty to 11."
She insisted that her son was at home all evening on the night of the murder, playing loud music and computer games in his bedroom.
In cross examination, prosecutor Mark Ellison QC said that in 1996 she told police she had seen Dobson 10 minutes later than that.
He said: "This 10 minutes could be an extremely important 10 minutes between half past 10 and twenty to 11, because the people who attacked Stephen Lawrence could have been back in their homes by then... You saw Gary wearing not very much in the kitchen at twenty to 11 or a quarter to 11."
She replied: "Yeah."
"That I suggest was what you thought in 1996. Is there any reason why it's become half past 10 when you come to give evidence?," Mr Ellison asked.
"I'm sorry, give or take 10 minutes, about then," Mrs Dobson said.
Earlier, Dobson, 36, said he did not hold racist views at the time of the murder, despite being seen making racist comments in a police surveillance tape shot the following year. Dobson and David Norris, 35, deny murder.
