A preliminary exam is underway for a father accused of murdering his three young sons. The boys, ages 9, 7, and 5, went missing 15 years ago and their bodies have never been found. Their father was previously convicted of unlawful imprisonment in connection to their disappearance.

He was scheduled to be released from prison when new charges were filed, including open murder and tampering with evidence. The case has taken a new turn with these upgraded charges. Further details about the case and the ongoing examination are available.
