what happened 3 things happened to Ichabod at the end of the story?

Ichabod is pursued by the Headless Horseman.

Ichabod races to the bridge where the ghost is said to disappear and not follow. Ichabod crosses the bridge and looks back, but he sees the Horseman, instead of disappearing, hurl his detached head at him. It knocks Ichabod off of his horse.

The next day, Ichabod’s horse returns to its owner’s farm, but there is no sign of Ichabod. A search party finds hoof prints and Ichabod’s hat, with a smashed pumpkin left next to it. Ichabod is never heard from again in Sleepy Hollow, although later on it seems that he is alive elsewhere and has told his story.
