I can back up this story.
Abdi told me that he was training and living with Sisay (and his wife) and Martin at the trials in Houston. He was excited about Ezykas performance in NY because he was kicking his butt in workouts. At the time no one had tested positive.
I remember how shocked Abdi was when he found out about Martin during his interview at the trials. Ezkyas positive wasn't revealed until June.
After the London Olympics the story changed and Abdi said they were both training partners briefly but denied living with them as I am sure he wanted to separate from all the drama.
