DIdn't know all those details. Important. AFAIK he stopped going to the gym when he went all radical Moslem.

Could be. Or he was involved in the murder. One would think he'd been considered as a suspect. He went to Russia "last year", from about Jan to June?, that would be 2012.

Here's the article:

Did Boston bomber murder his 'only American friend' in horrific triple killing in 2011?

Maybe both. If he was involved in the murder, that could be a reason why he stopped going and also had become radicalized.

The article says he started praying 5X a day whereas before the murder he only prayed one. Became more "devout".

I was thinking that if he murdered the man, it might have been as a result of his becoming a “devout” Mozlem. Since both events seem to have happened around the same time, plus the not going to the gym any more.

"Did Boston bomber murder his 'only American friend' in horrific triple killing in 2011?"

Very interesting article with lots of details. It's also interesting how the UK and Canadian papers routinely "out scoop" our local papers.
