While we knew little about Loibl at the time of the news, TMZ has since spoken to his former colleagues at US electronic store Best Buy, who have painted a disturbing picture.

According to them, Loibl was infatuated with Grimmie and went to great lengths to ensure she wouldn't be able to resist him.
The colleagues told TMZ he'd changed his appearance for the singer, going so far as to get hair transplants and have Lasik eye surgery. He also went on a vegan diet in an effort to slim down.
