Christina Grimmie's brother breaks silence with heartbreaking Facebook post

ORLANDO, FLORIDA. (WDAM) - The brother of a former "The Voice" finalist broke his silence on Facebook less than 24 hours after tackling the gunman who took his sister's life. 

Marcus Grimmie penned an emotional post, remembering his sister as his partner in life.

"Christina was more than my sister," Marcus' post read. "A superstar. A goofball. But above all...she was my baby sister."

Marcus has been hailed a hero for tackling the man who shot his sister.

Orlando Police Chief John Mina said at a news conference that the suspect, identified as 27-year-old Kevin Loibl of St. Petersburg, Florida, didn't appear to know Christina personally.

Christina was doing a meet-and-greet after her concert at The Plaza Live in Orlando, Florida when Loibl opened fire at her autograph table. According to police, the gunman attended her show specifically so he could attack her. 

Marcus immediately tackled Loibl, who then shot and killed himself during the struggle, according to police.

Police credit Marcus' heroic actions for preventing the gunman from hurting others.

There were around 120 people at the concert venue at the time of the shooting.

"I honestly don't know what I'll do without her," Marcus said in his post.

Marcus is asking all his sister's fans to comment under the post with pictures of her.

"The support has been crazy, and I do feel a peace," Marcus said.
