The trial of a West Michigan father in the disappearance of his baby daughter has been rescheduled for April.

The Ludington Daily News reported 21-year-old Sean Phillips of Victory Township is scheduled to go on trial April 16 in Mason County Circuit Court in Ludington. The charges are unlawful imprisonment and parental kidnapping.

Earlier scheduled trial dates were postponed.

Katherine Phillips was 4 1/2 months old when she last was seen June 29, 2011, with Phillips. Katherine lived with her mother Ariel Courtland at an apartment in Ludington, about 80 miles northwest of Grand Rapids.

Extensive searches haven't turned up the girl.
