Three days after the deadly shooting at Brown University, officers received an anonymous tip that stuck out from a flood of information. It directed authorities to a post on Reddit.

“I’m being dead serious. The police need to look into a grey Nissan with Florida plates, possibly a rental,” the Reddit user posted, according to an affidavit filed by the police in Providence, Rhode Island.
