We reported on this as it happened, where a RIM employee was stabbed at a party for BlackBerry Messenger, has died from his wounds. Philip Sherriff, one of RIM's UK employees, died on Sunday. His attacker is believed to be Ashley Charles and has already been charged with attempted murder.
What motivated Charles to stab Sherriff is not known, and the court hasn't made this clear, either. RIM has said in a statement through Twitter, where they gave condolences:
Our thoughts are with his family and those close to him and we ask for the respect of their privacy at this difficult time.
Our thoughts go out to Sherriff's friends, family and colleagues. Such an avoidable, yet unescapable event where a life was taken when it didn't need to be. Let's hope they find closure, and justice, soon.
