UPDATE: The Ingham County sheriff says a 15-year-old girl who went missing on Sunday has been found safe, unharmed, and apparently in the company of friends.
The FBI and Michigan State Police joined forces to help find Marissa Bolles after a call on Thursday afternoon demanding a ransom of $5,000 for the girl.
But authorities say the caller never told them where to send the money.
There was also a suggestion she was with a man in New York state - but after sending officers in Rome, New York, to a man's house - that lead didn't pan out.
The sheriff says they used a chopper and tracking dogs along with more than three dozen law enforcement officers in Michigan to try and find her.
They found Bolles just before 10 p.m. in a trailer on Lansing's west side. She was found in the company of six other people.
The sheriff says Bolles was never in danger, though it's not totally clear what her role in the situation was. Investigators were talking to Bolles and her friends late Thursday night to piece it all together.
