A man accused of the 2003 murders of a seven-year-old girl and the man she thought was her father has appeared in court.
Toni-Ann had been visiting Mr Byfield when they were shot
Joel Smith is charged with shooting Toni-Ann Byfield and Bertram Byfield in Harlesden, north-west London.
Toni-Ann became one of Britain's youngest gun crime victims when her body and that of Mr Byfield were found in a bedsit on 14 September 2003.
Mr Smith, 31, was remanded in custody until a hearing on January 23.
Police did not reveal details of the court for "operational reasons".
Toni-Ann, who had been raised in Jamaica, arrived in the UK in 2000 and had been in the care of a foster family in Birmingham before her death.
She had been allowed to go to London to visit Mr Byfield, a convicted drug dealer also known as Anthony Pinnock, while the family were on holiday.
The day she died she had been out shopping with him for a new school uniform.
DNA tests during the post-mortem examinations revealed that Mr Byfield was not in fact the biological father of Toni-Ann.
Her case was recently highlighted with a march through Brent, north-west London, by the families of shooting victims demanding an end to gun crime and appealing for information.
Four people have been arrested over the past few days in London and Merseyside.
Operation Trident detectives, who specialise in tackling gun crime amongst London's black communities, charged Mr Smith, of no fixed address, with murdering both Toni-Ann and Mr Byfield on Thursday.
A 22-year-old man, a 28-year-old woman and a 30-year-old man have been released on police bail.
