I was told (who really knows the truth?) by someone very close to the situation, that until that Monday evening all they had was a picture of the girl kissing Schaap while sitting on a 'gator' at his farm house along with the knowledge that he had broken many of his counseling policies. His staff reported it to Mrs. Schaap and Lapina. Lapina, Duff, Binney and Moore, then went to confront Schaap, force him to take a sabbatical and to get some help.... they found him belligerent, angry, prideful and vulgar. Duff walked away thinking, 'this man can no longer be my pastor'. Lapina, (I was told, influenced heavily by Decoster ) still wanted to go the sabbatical route.
That Monday, all the other photos came out and it became clear, to all that Schaap had to be fired and the matter reported to the authorities. Tuesday morning, the staff members went to the Sheriff and turned it all over to him.
As far as the other staff member, he was moved from CFO at the college to Risk Management at the church...and that's a totally different story.
