DARIEN - A community is saying goodbye today to a Darien teen who died unexpectedly last week.

Hundreds of people turned out at the Saint Thomas More Church in Darien today to pay their respects to 14-year-old Andy Pena.

The teen died after school officials say he collapsed on a treadmill while visiting Boston for his brother's swim meet.

Those who knew and loved him say he was well-liked at Darien High School and they're still dealing with the shock.

The exact cause of death has not been determined yet.
