ROTHBURY, Mich. — The FBI has publicly joined the investigation into a baby's death at last month's Electric Forest Festival in Rothbury.
The bureau and Michigan State Police released new information on the case on Monday along with a plea for more people to come forward with information.
The newborn was found dead inside a porta-potty in a camping area on festival grounds by a maintenance worker on Sunday, June 28.
The baby was no more than 28 days old, according to state police.
An autopsy of the child determined the infant was born alive and was medically able to survive outside the womb, said state police.

How will detectives investigate the baby death at Electric Forest?
Last week, state police announced they interviewed a woman from the Muskegon area who may have had information about the baby's death, but after talking with her, investigators ruled her out of the case.
Michigan State Police and the FBI's Detroit Field Office continue to investigate what led up the baby's death and request anyone with information on it to contact them. To encourage tips, the FBI is offering a reward of up to $15,000 for information that leads to anyone responsible.
"We understand the desire for additional information," MSP Lt. Pat Agema said to FOX 17 on Monday. "But certain information prematurely could compromise the integrity of the investigation."
"We do remain committed to conducting a thorough professional investigation, and will provide verified information when it is appropriate to do so," Agema said. "Our focus remains on seeking the truth."
