Police investigating the murders of a seven-year-old girl and her father have said they may have been killed over a drug debt. Toni-Ann Byfield and her father Bertram, 41, were found dead in a bedsit in Kensal Green, north-west London, four months ago.
Detectives believe Toni-Ann, who was shot in the back, may have been killed to stop her identifying the gunman.
It is thought Mr Byfield had been involved in the supply of drugs.
