Answer:
Katrina married Brom after the disappearance of Ichibod
Step-by-step explanation:
By the following night, Ichabod had mysteriously disappeared from the town, allowing Katrina to marry Brom, who commented that she knew too much about the events when Ichabod's story was told in the town. In fact, the only elements found about the teacher's disappearance were his horse, his hat and a mysterious shattered pumpkin in that same place.
Although the nature of the Rider is open to free interpretation, the story suggests that the rider was actually Brom (an agile and experienced rider) in disguise.
