Human remains were found in a suitcase in a creek on the near southeast side of Indianapolis.
People walking by spotted the suitcase near 2500 Villa Avenue on Monday afternoon. They opened it, found the remains and alerted police.
Police are not saying the age or gender of the person, but they did say the remains are not of an infant or child.
Authorities said they will not release the identify of the person until next of kin are notified.
Investigators are still trying to determine how the person died, but the circumstances are clearly suspicious.
