Amy Baker, the woman who helped authorities solve the disappearance of foster child Marcus Fiesel, is expected inside a Kentucky courtroom today.

Baker is facing charges in Maysville, accused of helping dispose of Marcus' remains in the Ohio River.

The hearing today is a preliminary hearing for Amy Baker. A few things could happen during the hearing. She could accept a plea deal with prosecutors or go forward with a trial.

Baker is charged with tampering with evidence in the death of 3-year-old foster child Marcus Fiesel.

Ohio authorities gave Baker immunity for testifying against Liz and David Carroll, the couple convicted of killing Marcus.

Baker, 26, was the Carrolls' live-in girlfriend. Investigators said the Carrolls burned Marcus' remains and dumped them in the Ohio River after stuffing him inside a closet where he died last August.

Baker has reportedly said she would confess to the tampering with evidence charge and admit she helped dispose of the remains, if Mason County prosecutors would agree to no jail time.

Kentucky officials prosecuted the "star witness" in the Ohio case because the remains were dumped in the Ohio River, which is owned by the state of Kentucky.

Baker is no longer in the Mason County Jail. Her mother posted a $5,000 cash bond a few weeks ago.
