The three boys were celebrating their friend's 13th birthday

Services will take place in memory of Josh Bartlett and Marshall Haynes, both 13, who died with their friend Liam Hastings, also 13, on 28 May.

The Citroen they were in collided with a Honda on Oxford's A4142. The Honda driver, Howard Hillsdon, 21, also died.

Four boys, aged 12 and 13, who were also in the Citroen and its 45-year-old female driver remain in hospital.

The funeral of Josh Bartlett is due to take place at the Church of the Holy Family, Blackbird Leys, Oxford, at 0930 BST.

Mother 'critical'

The service for Marshall Haynes is due to take place at St James Church, Cowley, at 1400 BST.

On Monday, the funeral for Liam Hastings is due to take place at Oxford Crematorium, Bayswater Road, Barton.

The crash, which involved five cars, is thought to have happened when the Citroen Xsara, driven by the mother of one of the surviving boys, crossed the central reservation of the A4142 eastern bypass.

It is then thought to have collided with Mr Hillsdon's Honda.

The surviving boys, Conor Hunt, 12, and Jake Proper, Aiden Wood and Anton Dublin, all 13, are all being treated at the John Radcliffe II Hospital in Oxford.

The mother is in a critical condition in the Great Western Hospital in Swindon.
