Less than a week after her shocking and senseless killing in broad daylight and in front of an army of fans, some truly chilling detail has been revealed about the man behind the murder of Christina Grimmie.
It's claimed that killer Kevin Loibl was an obsessive fan of the musician, YouTube star and The Voice US contestant, and had become so completely infatuated with Christina that he'd even gone as far as getting surgery to try and make her fall in love with him.
According to TMZ, gunman Loibl underwent invasive hair transplants, laser eye surgery and lived by a vegan diet to try and lose weight, in the hopes that changing his appearance would lead to a romance with Christina.
His Best Buy co-workers have revealed the extent of his scary obsession, explaining that not only did he listen to her music constantly, but he even spoke about his plans to marry her one day.
Loibl apparently attended one of her shows back in March and "hinted" that he'd met her, as well as claiming that he and Christina had played online games together at home - something which a source lose to her has insisted was not true.
Co-workers admitted that they'd teased Loibl about his complete infatuation, and told him that he'd never win her affections as she already had a boyfriend. It's thought that the comments had "enraged" him.
With Christina's fans, family and celebrity friends rallying together to express their sorrow and help fundraise for her loved ones, a funeral is set to be held later to this week to mark her tragic passing.
