MILWAUKEE -- Samy Mohamed Hamzeh worked at 9Round Kickboxing Gym in downtown Milwaukee. The owner says he worked there for a short time, but was fired last week. She said he wasn't a good fit.
His former clients are shocked their trainer is a terror suspect.
"I did not see that coming at all," said Emily Schuster.
"I was like 'oh my gosh that's really scary.' It's a little close to home when you think about everything with the extremists and you don't think that it would be so close to home and somebody that you know," explained Kiela Hoeldel.
The women worked out with the 23 year old early last week.
"He was always encouraging and always pushing us to go harder," said Schuster.
They say Hamzeh was a great trainer, but on the quiet side.
"He wasn't very conversational," explained Hoeldel.
Hamzeh worked for a valet company on and off over the last three years. The manager says he is dumbfounded by the arrest.
