Sean Phillips, a 23-year-old Michigan father, has been officially charged with the murder of his baby daughter, two years after "Baby Kate" disappeared.
An open murder charge was filed Friday against Phillips. Katherine "Baby Kate" Phillips was last seen on June 29, 2011, at the age of four months.
Baby Kate remains missing to this day.
The infant's disappearance riveted western Michigan after Phillips allegedly took off with the girl following an argument with her mother, Ariel Courtland.
Phillips was arrested the next day at his parents' house, but there was no evidence of Baby Kate. Now "new evidence" has been found to support the charge.
