Update at 4:20 p.m.: Police have identified the suspected gunman who killed 22 year-old singer Christina Gimmie (and then himself) as 27 year-old male Kevin James Loibl. They say that Loibl did not know Grimmie personally, but that he traveled to Orlando from another city in Florida with the intent of shooting her.

"She was doing a meet-and-greet, just signing autographs and selling merchandise. This white male approached her and opened fire, striking her," Orlando Police Chief John Mina said at a news conference, according to The Associated Press. "We believe he came here to commit this crime." The suspect was carrying two handguns, two loaded magazines and a hunting knife.

According to The AP, "the suspect had made travel arrangement to come to Orlando alone, as well as travel arrangements to go back home, but he didn't have a car."

According to CBS

, "Detectives were searching the suspect's cell phone and social media accounts looking for clues as to a motive, Mina said, but they weren't aware of any history of stalking of Grimmie by the suspect."

The hashtag #RIPChristinaGrimmie has been trending on Twitter for most of Saturday.
