Kara Alongi gained hundreds of followers after asking people on Twitter to call 911 Sunday. People re-tweeted her message and the hashtag "(hash)helpfindkara" trended on the social network.
The Union County Prosecutor's Office says a cab driver positively identified Alongi as his passenger and told officials he drove her to the Rahway train station.
The Star-Ledger also reported that Alongi was photographed by a security camera at the station.
The 16-year-old's parents called Clark police when they returned home and saw she was gone.
The prosecutor's office says Alongi might feel she'll be in trouble for causing a panic. However, authorities say all everyone cares about is seeing her home safe and sound.
