On every birthday, Christmas and Mother's Day, Margaret Nwabuko has a card bearing the name of murdered son Joseph.
Two years after he was gunned down by an armed raider in Birmingham city centre, his brother Johnson feels compelled to add his name to the cards.
"He's not here but he would have wanted to send a card to her," he said. "I have to do it."
West Midlands Police are still no further forward in finding the armed gang which robbed a Securicor delivery vehicle at the Nationwide Building Society in the Bull-ring at about 11.20pm on February 9, 2004.
Yesterday, Johnson Nwabuko made a new public appeal for information, imploring anyone who knows anything to "show humanity and take away this grief away from my family and myself".
The 38-year-old added: "I don't want my brother to die in vain. It has been two years since my brother's murder and I have to say I am still in shock, my mother and father are still in shock. It's on their faces. They try and hide their pain but it is still there."
Detectives believe Joseph was shot with a silver .357 Magnum handgun, moments after three men robbed security workers restocking cash machines.
Detective Chief Inspector Keith Wilson, leading the hunt, said Joseph walked towards the gang as they fled down Worcester Street.
One of the raiders told the armed gang member to "shoot him", at which point he was blasted in the chest.
It is believed the student may have been trying to note the registration number of the getaway car.
Det Chief Insp Wilson said the vehicle, a top-of-the-range silver Volkswagen Golf 2.88 V6 4Motion, had still not been found and appealed to anyone who had information about its false plate - CX02 WOX.
Joseph, aged 28, had moved to Birmingham from Walsall two weeks before the shooting.
He had been out walking through the city centre when he came across the raiders, who smashed their way through glass security doors and took cash from guards.
Johnson said Joseph was a "bubbly young man in the prime of life" and naturally inquisitive.
"What hurts me most is he was innocent, he was just doing his own thing but he was in the wrong place at the wrong time and was callously, brutally murdered. They didn't have to kill him, only the killers know why they took him away from us. They don't deserve to still be on the streets. My son and daughter will never see their uncle again, my two-and-a-half year old son will never know him."
He added the family was finding it hard to cope knowing the gang had not been brought to justice and admitted he and his father found it difficult to visit Joseph's grave.
"It has been horrendous. You try and get closure but it is impossible to be at peace with yourself when the offenders are still living their life.
"I don't want to be bitter but I can't get away from it. The pain's real, it's as raw as it was when it happened.
