THE last weeks of suicide bomber Jermain Lindsay saw him undergo a drastic change.
His widow, Samantha Lewthaite, claimed today that the teenage killer turned from a loving father to a cold, aggressive man.
In an interview in the Sun, she said she believed his actions were to distance himself from her and their child before he was able to kill himself and 26 others on a King's Cross train.
Lindsay, 19, who had been brought up in Huddersfield, was one of the four suicide bombers who struck in London on July 7.
The gang was led by Mohammad Sidiqque Khan, of Thornhill Lees.
His wife, with whom he had lived in Huddersfield, has been left with their two children - Abdullah, 17 months, and baby Tuqayyah, born just 16 days ago.
She told how Lindsay began to change up to eight months before the murders.
She said Jamal, the Muslim name he had taken, would spend long periods in mosques in London and in Leeds.
"When he came back he was so different. He was snappy and verbally aggressive," she said.
"It was a turning point, I saw a different Jamal from now on. It was nothing instant but gradual over the months as his attitude to me changed. It was as if he was driving me away."
His erratic behaviour included refusing to pray with her and getting rid of his Muslim robes and wearing Western style clothing.
He lost his job as a carpet fitter, but suddenly seemed to have lots of cash.
He also spent long periods on the internet and she believes he was "chatting" to other extremists.
"He said he just wanted space and began to seclude himself from me.
"Jamal still prayed five times a day, but didn't want me to pray with him. I had no idea what was happening in his life".
Lindsay's last actions were to stage a text message from another girl. It caused Samantha to throw him out of the house - a move she took hours before he made his fatal last journey.
