A day of prayer has got under way in Bristol a year on from the murder of landscape architect Jo Yeates.Miss Yeates, 25, was killed by her neighbour Vincent Tabak in her Clifton flat. He strangled her then left her body by a roadside verge.Tabak was jailed for 20 years at his Bristol Crown Court trial where it was revealed he had viewed violent porn.Christ Church, on Clifton Down Road, near Miss Yeates\'s flat, has opened for people to talk about what happened.The Reverend Paul Langham said: \"It\'s a small way of marking a dreadful day in our community\'s history.\"Mr Langham said there was a card - which will be sent to Miss Yeates\'s parents - at the church that members of the public could sign.\"As we mark the anniversary today it is still incredibly fresh for people.\"I think the sense of shock that people felt last year is coming alive again as we remember, and particularly as we are in the middle of a season of joy and rejoicing.\"Yet it is a stark reminder that for one particular family, and for others, Christmas can be a great time of sadness.\"The church will remain open until 17:00 GMT.\"There was a great feeling from everybody that they wanted to do whatever they could to send best wishes and prayers to the family,\" he added Dog walkers discovered the body of Miss Yeates, originally from Ampfield in Hampshire, on Christmas Day in Failand, North Somerset.She had last been seen by colleagues at the Bristol Ram pub in Park Street, Bristol, at 20:00 GMT on 17 December.Her father David Yeates said in a recent interview with the BBC that the family would find Christmas difficult.He said: \"She loved Christmas - that was the best time of the year.\"She enjoyed the whole razzmatazz to do with Christmas and that\'s why Christmas - her being found on Christmas Day - was so poignant.\"
