This is going to be one lesson that Marisa Martin will remember for a long time. Sometimes even jokes on social media can cost a person.

Last night a gunman opened fire at the library on the campus of Florida State University. Three students were wounded, and the gunman was shot down by police according to the Washington Post.

Just be mindful of what is being posted on social media. Even if a tweet or post is deleted, it doesn't mean that it's gone forever.

Unfortunately for Martin, that is showing to be completely true.

Sometimes it's just better to live by the Herm Edwards rule of social media: "Don't Push Send."

No statement has been released by ESPNU regarding her status as an intern campus reporter.
