RAYMOND ARMSTRONG, the model on trial for allegedly strangling a longtime friend in the man's Grays Ferry home in September 2008, at first fought back tears and then burst out sobbing Thursday while pleading his innocence on the witness stand. Armstrong, 35, who has modeled for Target and Kenneth Cole, told the Common Pleas jury that while dozing in a second-floor bedroom after becoming ill, he awoke after realizing he was being sexually assaulted by the homeowner, Anthony Williams.
