Sean Mercer

He had one brother, Owen (born 1990).

On 22 August 2007, Rhys Milford Jones, an eleven-year-old English boy, was murdered in Liverpool while walking home from football practice.

Jones, who would have turned 12 five weeks after his death, had just left Broad Square Primary School on the Norris Green housing estate, and was due to start secondary school at Fazakerley High School in September 2007.

His former headteacher and neighbours said he was a friendly and popular boy who loved football.

Jones, who played for the Fir Tree Boys football club, was on his way home from football practice alone on the evening of 22 August 2007.

As he was crossing the Fir Tree pub car park on the Croxteth Park estate, Liverpool, a hooded youth riding a silver mountain bike approached.

He then held out a Smith & Wesson handgun at arm's length, firing three shots, later determined to be the wrong bullets for the gun.

It was originally believed that one of the shots hit Jones in the neck, but during the trial, the pathologist revealed that the bullet had entered his back above his left shoulder blade and then exited from the front right side of his neck.

Melanie Jones rushed to the scene when she heard that her son had been shot.

By the time she had reached him, he was unconscious.

Paramedics tried for 90 minutes to resuscitate him, but he was pronounced dead shortly after arriving at Alder Hey Children's Hospital.

Local radio station Radio City 96.7's programmes on the night of the incident, in particular the 10pm – 2am show, was dedicated to an amnesty for witnesses and a talk on gun crime.

Radio City also launched their anti-gun-crime campaign (backed by the Jones family), In Rhys's Name Get Guns Off Our Streets, after the incident.

Detectives arrested and later released four people aged between 15 and 19 in connection with the crime.

Two further arrests (both teenagers) were made, but both suspects were soon released on bail pending further enquiries.

The police appealed to the public for information, stating that they needed help in finding those who had committed the crime.

The murder weapon was described as a black handgun with a long barrel.

More than 300 officers and gun crime specialists were deployed in the hunt for the killer.

Steve and Melanie Jones made a fresh appeal for witnesses to come forward on 19 September, four weeks after the murder, which was reconstructed on Crimewatch on 26 September.

In the episode, Melanie Jones appealed directly to the murderer's mother to turn her son in.

It led to 12 people calling into the programme, all of whom gave police the same name.

Despite reports that the killer's name was widely known and had appeared on internet sites and in graffiti, police continued their appeal for witnesses to come forward.

Sean Mercer, aged 16 at the time of the shooting, went on trial on 2 October 2008, and was found guilty of murder on 16 December.

Mercer was sentenced to life imprisonment serving a minimum of 22 years.

Rhys Jones was the second-born son of Stephen (born in Liverpool) and Melanie Jones.

On 15 April 2008, Merseyside police confirmed that 11 people (all aged between 17 and 25) had been arrested in connection with the murder.

Six more suspects of a similar age were arrested the next day in connection with the murder; one for murder and the other five for assisting an offender.

One of these men had already been charged with possessing a firearm.

All six of them were remanded in custody by Liverpool Magistrates on 17 April 2008.

Another man was charged in connection with the case on 18 April 2008, and remanded the same day.

On 16 December 2008, at the end of a nine-week trial in the Crown Court at Liverpool, Sean Mercer (a member of the Croxteth Crew gang) was found guilty of murder.

Mercer, by then aged 18, was sentenced to life imprisonment, being ordered to serve a minimum term of 22 years, which is set to keep him in prison until at least 2030 and the age of 40.

Other gang members James Yates, Nathan Quinn, Boy "M" (who could not be named as he was still under 18), Gary Kays, and Melvin Coy were convicted of assisting an offender.

Another defendant aged under 18, Boy "K", later revealed as Dean Kelly, was convicted of four related offences.

Kays and Coy were both sentenced to seven years.

Sentencing for four of the defendants was delayed until the following month.

In January 2009, Yates was sentenced to seven years, Dean Kelly to four years, and Nathan Quinn to two years.

A 16-year-old was sentenced to a two-year supervision order.

Parents of the gang members, including Mercer's mother and the parents of Yates, were later tried and convicted for perverting the course of justice.

On 28 October 2009, Yates had his sentence increased to 12 years imprisonment, following a referral to the Court of Appeal by the Solicitor General Vera Baird QC as being "too lenient".
