44-year-old Peter Perfect was supposed to drop off his two daughters at the home of his estranged wife after church on Sunday, but that never happened.
Police believe Perfect may be headed out of state with six-year-old Aleah Perfect and two-year-old Amara Perfect.
The three are believed to be in Perfect’s 2003 Saturn.
The Maine license plate number is 3070 LH.
Perfect was served with divorce papers earlier this month.
Anyone with information on their location should call state police at 1-800-432-7381.
