This is interesting though
In 2017, The Sunday Times reported that Bellfield's ex-wife Johanna Collings had told investigators in the Delagrange case that he was with her on the day for her 25th birthday, the time of the Russell murders, and had spent all day in Twickenham and Windsor, 100 miles away from the scene of the murders which occurred at around 4.30pm. It was an alibi which detectives found credible.[45] Collings had helped detectives convict Bellfield for his previous murders, such as in the Milly Dowler murder, giving evidence that he knew the area where her body was left well.[46] In regards to the Russell murders, however, she clarified in a BBC documentary in 2017:
My daughter was born in '96 and that was the day of my birthday. He [Bellfield] never left my side, all day and all night, so there's absolutely no way he could have got from Twickenham, where I lived, or Windsor, where I kept my horses, to Kent, done what they say he did, and got back without me not knowing he was there. I can hand on my heart, I hate to say it, but I can say hand on my heart he didn't do it.[46
