ORLANDO (CNN) — Florida authorities answered one of the major questions in the shooting death of Christina Grimmie, the 22-year-old singer who made her name on NBC's "The Voice."

The man who killed her was Kevin James Loibl, 27, of St. Petersburg, Florida, according to Orlando police.

But they didn't give any background on Loibl or offer a possible motive.

CNN affiliate WFTS photographed a handwritten note posted on Loibl's family home. It reads, "Deepest sorrow for lost (sic) to the family, friends and fans of the very talented, loving Christina Grimmie. No other comments."

Grimmie was signing autographs late Friday after a show at The Plaza Live theater when a man approached and opened fire, police spokeswoman Wanda Miglio said.

She was rushed to a hospital, where she died.

'More than my sister'

Loibl fatally shot himself after the singer's brother, Marcus Grimmie, tackled him, police said in a statement. About 120 people were at the meet-and-greet, and the brother's quick action may have saved other lives, police said.

Marcus Grimmie paid tribute to the singer in a Facebook post, saying he has no words.

"Christina was more than my sister. She was a partner in life," he posted. " A superstar. A goofball. Introverted. And a friend to everyone. Genuinely. But above all...she was my baby sister."

Hand guns, knife

The shooter had two handguns, two additional loaded magazines and a large hunting knife, police Chief John Mina said.

Mina said investigators were going through the man's computer, phone and other belongings to see whether they can find information about a motive. There's no evidence Grimmie and Loibl knew each other, police said.

Police said the suspect drove to Orlando, apparently to commit the crime, and "then had plans to travel back to where he came from."

Theater suspends shows

It's unclear how the gunman got a gun into the venue or whether attendees were checked for weapons.

"We don't know if he was just a crazy fan that followed her on Twitter or on social media," Miglio said. "We really don't know ... it's undetermined at this point."

Security measures are in place at The Plaza Live, police say, but there are no metal detectors and people are not patted down.

"As far as security, The Plaza does have security guards who wear polo shirts. They are unarmed," Mina said. "They do check bags and purses as people enter."

The Plaza Live issued a statement extending condolences to the victims and indicating all activities and events have been suspended "until further notice."

"Our thoughts and prayers are with the families of those lost as well as those that witnessed and aided in the recovery after this senseless act," the statement said.

Heartbroken fans

Grimmie posted a video hours before her last performance in which she jovially invited fans to see her show.

She was discovered on YouTube, where she amassed more than 3 million followers. Grimmie went on to win a spot on Season 6 of NBC's "The Voice" after her show-stopping performance of Miley Cyrus' "Wrecking Ball" during a blind audition captivated the attention of all four contestant judges.

The rising star finished third in the overall contest but went on to share her voice with the world.

Fans, friends and celebrities showed an outpouring of sorrow on social media using #RIPChristinaGrimmie.

One of her friends and mentors was singer Selena Gomez, who tweeted: "My heart is absolutely broken. I miss you Christina."

"As you've seen all over social media, anyone who ever came across her or knew her, knows that she was just a truly good person, somebody you loved to be around, somebody who cared about the people around her and the world around her, it's just a huge tragedy, "The Voice", Season 6 winner Josh Kaufman told CNN's "New Day" on Saturday.

The band that was touring with Grimmie, Before You Exit, said on Twitter that its members are heartbroken.

"Christina was such a loving, caring, beautiful person with the biggest heart," Before You Exit said a statement attached to one of its tweets. "She was an absolutely incredible musician and an even better friend."


Christina Grimmie was destined to be a star from the start.

When she first performed on the NBC show "The Voice" two years ago, some of the judges' eyes flew open. They cheered wildly as they savored her every note -- swiveling their chairs forward and pressing their buzzers to express their approval.

Here are five other things to know about Grimmie, the 22-year-old singer shot dead after her concert in Orlando:

She was a digital phenomenon

Grimmie's fame was not limited to concerts and festivals.

She was a digital powerhouse who amassed more than 3 million subscribers on YouTube. She was discovered when she was a teen six years ago on her YouTube page, where she belted out powerful renditions of famous cover songs. Her career has been on an upward trajectory since then, fueled by her memorable appearance on "The Voice."

"There are no words," "The Voice" tweeted after her death. "We lost a beautiful soul with an amazing voice. Our hearts go out to the friends, fans and family."

Her fans included superstars

Grimmie finished third on Season 6 of "The Voice," where her fans included some of the biggest superstars.

When contestants start on the show, four judges listen with their backs turned to the singer; by the end of the song, the performer will hope that at least one of the judges will have turned around, signaling they want him or her on their team for the remainder of the competition.

In Grimmie's first appearance on the show in 2014, all four judges wanted her. As she performed Miley Cyrus' "Wrecking Ball," singer Usher, one of the judges, jumped from his seat and pumped his fists in the air. Country crooner Blake Shelton, another judge, tightly closed his eyes, taking in Grimmie's every note.

Since more than one judge wanted her, she had her choice. She ended up being a finalist on the team of Maroon 5's lead singer, Adam Levine.

She has also opened for Selena Gomez several times, and has performed on "Ellen."

She moved West to pursue her dream

Grimmie was not one to shy away from following her dreams. The New Jersey native moved to Los Angeles to pursue a music career.

She released her first album in 2011 titled, "Find Me," which debuted at number 2 on iTunes, according to her website.

Shortly afterward, she packed her bags and moved to the West Coast. She released her sophomore album, "With Love," and her career kept blossoming. Last year, she was selected as a rising star for Macy's iHeartRadio.

Despite her new home thousands of miles away, she mused about the pros and cons of both coasts.

"Los Angeles traffic is just the worst thing in the world. It throws off timing so much," she posted on her website. "However, it's always warm and sunny. New Jersey has absolutely terrible weather but the environment is really homey and chill."

She said no to skimpy outfits

Last year, Grimmie told a UK newspaper that she has no plans to wear overly skimpy outfits to sell albums.

"I've absolutely fought against having to be half-naked to sell a track," the Daily Record quotes her as saying.

"Someone asked me the same question five years ago and it was the same answer then. They say, 'We'll pay you this check if you sing this line or dress in this particular outfit. People tell you what you have to wear and do and I've never been a fan of it."

Her ties with Selena Gomez went beyond music

Grimmie told Seventeen magazine that she was discovered by the stepdad of pop star Selena Gomez.

She went on to form a fast friendship with Gomez, and credits the popstar with a lot of her life lessons.

"She's been really, really encouraging to me," Grimmie told the popular teen magazine.

"She really taught me two things. First: be yourself no matter who talks crap about you. She said, "You have to be yourself in every situation." The other thing is to keep going when you mess up live."
