A man charged with stabbing four people on an Amtrak train in Niles has been declared incompetent to stand trial.

Judge Dennis Wiley made the ruling Monday in Berrien County Trial Court in Niles after reviewing the results of a forensic examination performed on 45-year-old defendant Michael Darnell Williams.

The Saginaw man is facing four counts of assault with intent to murder.

Although Williams was declared incompetent at this time, the court order signed by Wiley says that there is substantial probability that the defendant will attain competency to stand trial if provided a course of treatment.

Williams has been placed in the custody of the Michigan Department of Mental Health, which will supervise his treatment.

A status report has been scheduled for June 15 in Niles to check on Williams’ progress.

Williams allegedly stabbed four people on an Amtrak train that was stopped at the Niles Amtrak station on the evening of Dec. 5.

Passengers reported that Williams was acting erratically in the moments leading up to the stabbing. The Niles Police Department was dispatched to the scene and used a taser to apprehend the suspect.

Williams later told Niles Police detectives that he remembered talking to a man on the train who turned into a demon, according to the complaint warrant. Williams then told detectives that he had to fight the demon, but didn’t remember what happened next.

The maximum penalty for assault with intent to murder is life in prison.
