A friend of the gunman who shot "The Voice" singer Christina Grimmie after an Orlando concert says his friend had developed a fixation on her within the last year.

A police report released Wednesday recounts an interview with Cory Dennington, who describes himself as the only friend of Kevin Loibl, the man police say fatally shot Grimmie on June 11. Loibl killed himself after the shooting.

Dennington told Orlando detectives that Loibl spent most of his time watching Grimmie on YouTube and that he constantly monitored her social media accounts.

Dennington also says Loibl had lost weight, got eye surgery and had hair implants to improve his appearance for her. Dennington worked with Loibl at a Best Buy store in St. Petersburg.
