Friend: Shooter had fixation on 'The Voice' singer

'The Voice' contestant shot, killed at Orlando concert

ORLANDO, Fla. – The investigation into the shooting death of "The Voice" star Christina Grimmie has been closed, officials said on Wednesday.

Grimmie was shot and killed while signing autographs after a performance at The Plaza Live in Orlando June 10 just after 10 p.m.

Orlando police said the case was closed and cleared since the suspect, Kevin James Loibl, died of a self-inflicted gunshot wound at the scene. Had Loibl lived, police said they would have charged him with first-degree murder.

A friend of the gunman who shot Grimmie 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 Loibl, the man police say fatally shot Grimmie on June 10. Loibl killed himself after the shooting.

The report released Wednesday stated that Loibl took a cab from St. Petersburg to Orlando and stayed in the Courtyard Marriott in downtown Orlando. The hotel front desk worker described Loibl as "strange."

"He made plans to come to Orlando and took a taxi to come here, stayed in a hotel and went to the Plaza Live that night," said Wanda Miglio with OPD.

Grimmie, 22, who performed with a band named Before You Exit, was signing autographs about 30 minutes after the concert ended when Loibl walked toward her and shot her, police said.
