A £25,000 reward has been offered for information leading to the killers

Police have said the net is closing on the killer of a lorry driver who died when he was hit by a brick.
Surrey Police made a "stark promise" on Tuesday to the person who threw a brick through the windscreen of Michael Little's lorry on the M3 on the Surrey/Berkshire border.
"We have your DNA on the National DNA Database and we will identify you," a statement said.
Mr Little, 53, suffered heart failure after the missile hit him on the chest at about 0030 GMT on 21 March.
A police spokeswoman said detectives were still confident three months later that the killer would be caught.
We are building a clear picture of the events that led to Mr Little's death

Detective Chief Inspector Graham Hill, leading the inquiry, said: "We are building a clear picture of the events that led to Mr Little's death and, in doing so, are identifying other criminal activity in the area.
"The National DNA Database has more than two million profiles on it and these are added to on a daily basis."
Police believe the murder could be connected to an attempt to steal a Renault Clio parked in a driveway in Brackendale Road, Camberley, on the same night.
A DNA sample was obtained from blood found on the car.
DNA swabbing widened
A spokeswoman said 162 targeted men from the area had already been screened through DNA swabbing.
The search area will now be widened to include an area south of the footbridge over the M3 and an area of Frimley.
Officers are also visiting targeted schools in the Camberley and Frimwell area to appeal directly to teenagers who may know who was responsible or have witnessed something on the night.
Flyers publicising a £25,000 reward offered by Mr Little's employers, Ford Motor Company Ltd, have also been circulated.
An appeal for information was made on the BBC's Crimewatch show in May.
