(Tom Gralish/The Philadelphia Inquirer via AP) (Newser) – Kevin Loibl was obsessed with The Voice singer Christina Grimmie before he murdered her last Friday, multiple co-workers of Loibl tell TMZ. The Best Buy Geek Squad employee claimed he met Grimmie at one of her shows in March and played online games with her, though a source close to Grimmie tells the gossip site the two were never in contact. Loibl's co-workers say he overhauled his looks in an effort to win her over, going on a vegan diet to lose weight and getting hair transplants and Lasik vision surgery. Grimmie's funeral will be held Friday in her home state of New Jersey, ABC News reports.
