I think it reads Ismael? Ishmael? (not sure, just heard it on the radio).
And now they are saying maybe He was Muslim.
I dislike talking about religion, but I wanted to mention what I just heard on the radio.
Edit: This is what I found online ...
He was found with the words "Ismael Ax" written in red ink on an arm, the Post reported law enforcement sources as saying. It was unclear what the words meant.
Neighbours, roommates and teachers described Cho as a withdrawn person who rarely spoke. Two students who said they were Cho's roommates said he had harassed several female students and once told them he wanted to kill himself, which prompted the roommates to report their concerns to the police.
