Two brothers involved in the brutal murder of a Bradford tourist in America are facing armed robbery charges.

The parents of Wilsden engineer Gary Colley - who was gunned down at a Florida roadside seven years ago - spoke of their outrage after police revealed the pair were responsible for another hold-up in North Florida.

Today, Mr Colley's mother Brenda Armitage described the pair as evil, adding: "I am not surprised something like this has happened. These people should never be allowed out."

Teenagers Cedric Green, Deron Spear, John Crumitie and Aundra Akins were convicted over 34-year-old Mr Colley's murder in 1997.

Now Green, 20, and his half-brother Spear, 21, are facing robbery charges following a grocery store raid.

Spear was arrested at his home in Tallahassee, Florida, but Green is still on the run.

On hearing the news Mr Colley's father Terry said: "It is sick. These people will do this again and again and someone else will lose a child as I have. They should be locked up permanently."

Gary Colley was shot dead and his girlfriend Margaret Jagger, then 35, was injured when they parked up at a highway rest stop in September 1993.

In a bungled robbery 14-year-old Akins frantically fired shots from a .38 calibre revolver.

The couple panicked and tried to reverse away, but a vehicle stolen by the teenage gang earlier that evening blocked their escape.

Akins showered their rental car with bullets. Miss Jagger was shot in the arm and chest but managed to scramble to safety.

She survived and returned to Florida to give evidence against all four teenagers at their trials.

Green, who was 13 at the time, was sentenced to a juvenile offender programme and 50 hours of community service after striking a plea agreement.

Spear was sentenced to eight years in a state prison after admitting conspiracy to commit armed robbery, but was released after serving two years.

Crumitie and Akins are still behind bars.

Mr Colley, of Morris Avenue, Brighouse, said: "It is hard to describe the way I feel. I cannot forgive them for taking Gary away. I just feel emptiness and bitterness."

Lieutenant Randy Squire, of Panama City Police today confirmed Green was still on the run and warned: "He's dangerous.

"He knows we're looking for him and he's almost certainly armed."
