What is the name of the sheriff who finds Bob Ewell's body?

The sheriff who finds Bob Ewell’s body is Heck Tate, Maycomb County’s sheriff. He discovers Ewell dead after the attack on Jem and Scout near the end of the novel.

Ewell has been seeking revenge against Atticus Finch after the trial of Tom Robinson humiliates him. On Halloween night, he attacks Jem and Scout as they walk home from the school pageant. Jem’s arm is broken, and he is knocked unconscious, while Scout is saved by a mysterious man later revealed to be Boo Radley.

When Heck Tate arrives at the Finch home, he has already determined that Ewell died from a knife wound. Atticus initially fears Jem may have killed Ewell while defending himself. Tate, however, believes Boo Radley was responsible for protecting the children.

To spare Boo public attention and prosecution, Tate says he will report that Ewell fell on his own knife. This decision connects Tate’s role as sheriff with the novel’s larger questions about justice, mercy, and protecting an innocent person.
