In 1993, a second person was tried for Royal's murder. As with the previous defendant, someone close to him having a connection to the man Royal had fatally stabbed (in this case his girlfriend, who was the sister of that man) was viewed as a motive, and he spent nearly 14 years in prison for the murder before his conviction was overturned in 2007.^[13]

Two people were charged in connection with Jackson's murder, but there was not enough evidence to prosecute. A third man who was also charged but whom the Crown Prosecution Service offered no evidence against later died, and his mother said that he never recovered from the trauma of his arrest and charge.

At the time of his murder, Jackson was suffering from cancer and did not have long to live.^[45][46]

Aged 22 at the time of his death, Johnson was the nephew of moors murders victim Keith Bennett, and had begun to embark on a life of crime within a few years of leaving school.^[37]

A former psychiatric nurse from Charminster, Dorset, was sentenced at the Old Bailey to nine concurrent terms of life imprisonment on 10 February 1994 for the kidnap, rape and attempted rape of a number of disabled women. He was also charged with the kidnap of Ramsden; however, due to insufficient evidence, the case was dismissed at a pre-trial hearing.^[69]

On 21 January 2013, 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.^[152] A former colleague of Brumhill's stood trial for his murder but was found not guilty in March 2017.^[153]

Links with convicted killer Stephen Griffiths and the murder of Michaela Hague in 2001 have been suggested.^[206] However, the prime suspect was prostitute killer Alun Kyte, who had killed two sex workers in December 1993 and March 1994, and was suspected by police of being responsible for many other such murders across Britain.^[59]

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. A verdict of "not proven" was announced when the retrial concluded.^[266]

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. The flats had an intercom system and Hewer's door had a peephole which she regularly used, so it is very likely that she knew her killer and willingly let him in.^[292][293]

At the 1997 trial, the other two accused, drug dealers from London (one of whom was the house owner's ex-boyfriend), claimed that when the four of them and Taylor were in a house together to try to reach an agreement, the woman and her brother, with Taylor in tow, left the house and said after coming back that Taylor was dead, while the woman and her brother claimed it was the drug dealers who did that. However, her brother did admit to putting the murder weapon down a drain in Peacehaven, east of Brighton. The drug dealers were found guilty of murder but their convictions were overturned on appeal in 1999. During the retrial, one of them admitted to a charge of false imprisonment but was freed because of time already spent in jail.^[330]

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.^[440]
