LUDINGTON -- Prosecutors say they are filing a murder charge against the father of a western Michigan infant missing since 2011.
State Attorney General Bill Schuette and Mason County Prosecutor Paul Spaniola say Friday that 23-year-old Sean Phillips faces one count of open murder.
Phillips was convicted of unlawful imprisonment last year in the disappearance of Katherine Phillips. She was 4 1/2 months old when last seen in the Ludington area, about 80 miles northwest of Grand Rapids.
Prosecutors say Sean Phillips took the baby from her mother because he feared a court-ordered paternity test would show he was the father.
He received a sentence of 10 to 15 years in prison and is appealing.
Investigators have said seeds and other material on Phillips' shoes could be crucial to locating a body.
