BBC Crimewatch to feature murder of 'Jock' Davison
Detectives hunting the killers of a former IRA commander are to make an appeal for information on Crimewatch tonight.
Gerard 'Jock' Davison was shot dead in the Markets area of Belfast earlier this month.
The 47-year-old was hit several times as he walked along a street in the staunchly republican district close to the city centre.
Superintendent Kevin Geddes from the PSNI serious crime branch said detectives needed more help.
"The investigation is progressing but we need more information.
"The opportunity provided by Crimewatch will hopefully generate calls from people who can help us apprehend the killer."
Davison, a grandfather and father-of-three, was targeted as he walked along Welsh Street towards a community centre on Tuesday, May 9.
Officers revisited the scene of the crime exactly a week later and renewed their appeals for information.
In this latest appeal police are expected to disclose new details about the gunman's movements and the weapon used.
As the IRA officer commanding in Belfast, Davison was one of the best-known republican figures in the city.
He backed Sinn Fein's peace process strategy following the 1998 Good Friday Agreement and was employed with the Markets Development Association as a community worker.
He was allegedly involved in the fight that led to the death of Belfast man Robert McCartney in January 2005 and was among three IRA members expelled following an internal investigation in the wake of the death. He was questioned by police but released without charge.
Davison's uncle, Terence Davison, was later acquitted of Mr McCartney's killing.
Mr McCartney's sisters, who were forced to move out of the nearby Short Strand, led a long-running battle for justice for the killing of their brother following a bar argument, which took them to the White House.
In an interview with the Belfast Telegraph earlier this month, they said their campaign for justice has ended with the Davison murder.
"We wanted Jock to face justice in a courtroom, not down the barrel of a gun," said Catherine McCartney. "But the type of justice we hoped for has eluded us. We will never see Jock standing in the dock now."
Crimewatch will be broadcast on BBC 1 NI tonight at 9pm.
Since the launch of Crimewatch in 1984, it has featured more than 4,000 cases, with one in three ending in arrest and one in five in convictions thanks to information from the public. It has featured some of the UK's most high-profile murders, including that of Sarah Payne, Sally-Ann Bowman, Joanna Yates, Stephen Lawrence and Jill Dando.
