Organist Alan Greaves murder: £10,000 reward offered 3 January 2013 Last updated at 15:35 A £10,000 reward has been offered by Crimestoppers for information leading to the conviction of the killer of a church organist on Christmas Eve. Alan Greaves, 68, of High Green, Sheffield, died three days after he was attacked while walking to St Saviour's Church for Midnight Mass. The father-of-four was found with a head injury near his home on Greengate Lane at about 23:15 GMT on 24 December. Two men arrested on suspicion of murder have been released on police bail. South Yorkshire Police said there appeared to be no motive for the attack. Det Supt Matt Fenwick said: "People must have been out and about in the village and someone must have seen or knows something about this assault. We'd urge them to come forward and help gain justice for the family. Vicious attack At a service following her husband's death, Mr Greaves's wife, Maureen, said she had wept over the "evil that has been done." She said: "I have not stopped crying for him and I know you have not stopped either." Roger Critchell, director of operations at the charity Crimestoppers, said: "This was a particularly vicious attack on an innocent man who was sadly in the wrong place at the wrong time. There's absolutely no explanation for the attack on Alan and we hope by offering this reward, someone who knows who did this will come forward with the information that can help bring the person or people responsible for it to justice.
