Lee Rigby's son speaks publicly for the first time and hopes to raise £10k for ... trends now Lee Rigby's son has spoken for the first time about the murder of his father in 2013 and how he will be completing a marathon in his memory. While only two years old when drummer Lee, of the Royal Fusiliers, was killed, young Jack, now 12, told The Mirror that exercising helps 'distract' him from his grief. 'Going on a long walk is a nice break and reminds me it's not all bad,' he explained. It was revealed that Jack, who had appeared at his father's funeral wearing a T-shirt bearing the words 'My Daddy, My Hero', was unable to speak for a number of months as a toddler as a result of the trauma. Jack said he will walk and run the May Marathon to raise money for the charity Scotty's Little Soldiers, which supports bereaved military children.

Jack's mother, Rebecca, 40, told the newspaper: 'Just because Jack was young, it doesn't mean he's forgotten Lee. 'He wants to show how even though he's grown up without Lee, he's not forgotten his dad.' Fusilier Rigby, 25, was run over and stabbed to death in broad daylight while walking towards his barracks in Woolwich, south east London. The attack was carried out by ISIS extremists Michael Adebolajo and Michael Adebowale, who reportedly picked the solider out at random as he was off-duty and wearing civilian clothes at the time. The father-of-one died as a result of multiple cut and stab wounds after the attack, fuelled by Adebowale and Adebolajo's extremist beliefs - described as a 'betrayal of Islam' at their murder trial in 2014. The murderers are understood to have expected to be killed by armed police at the scene and were hoping to be 'martyred'. Instead they were injured, arrested and stood trial for Lee's killing, where they were both given life sentences.

Fusilier Lee Rigby's wife Rebecca carries their son Jack from Bury Parish Church after attending the start of an overnight vigil on July 11, 2013 in Bury, England The father-of-one grew up on the sprawling Langley estate in Middleton, near Rochdale, and attended nearby Middleton Technology School. His mother, Lyn Rigby, said earlier this month that she still leaves an empty seat at the dinner table for her son. Meanwhile killer Michael Adebolajo was stopped from attending yoga sessions last year while in prison because bosses feared that he would 'spread extremist views' to other participants during classes. 'He was gutted. He thought yoga would relax him and improve his mental wellbeing,' a prison source told The Sun. Fusilier Rigby's son is now hoping to raise money for the charity that has helped him cope with his father's tragic death. Jack has already carried out some walks with his mother and his dogs in a local park, adding that his black cockapoo, Scotty, can only finish one lap. The charity Scotty's, which Jack's dog is named after, has allowed him to meet other children who have suffered a similar tragedy. Donate to Jack's fundraising marathon here.
