[115] On 21 January 2013, the day after the 20th anniversary of the murder, police announced they were reviewing the case and hoped that advances in forensic analysis and DNA profiling would bring the killer to justice.
[61] Cannon's partner was retried towards the end of 2001, at which hearing it was stated that had the defence team for his earlier trial called in their own forensic experts, they might have been able to put forth evidence to support his claim that the droplets of her blood on his clothing, rather than being spatter from bullet wounds, had been coughed up by her as he held her in his arms while she was dying.
[284] In an update on Crimewatch in 2015, police revealed that they had managed to trace everyone that had been captured on CCTV entering and exiting Hewer's block of flats that night except for one man, who as of the 2020s would be between about 60 and 70 years old.
[354] After a huge amount of press coverage and a 13-month investigation, police arrested Barry George, a convicted sex offender, for Dando's murder.
Sentenced to life imprisonment on 2 July 2001, George appealed against his conviction in November 2007 and was acquitted on 1 August 2008 following an eight-week hearing.
