Summarize Heck Tate's testimony. From his point of view, what happened on the night of November 21?Why did he arrest Tom Robinson?

The trial begins with the testimony of the sheriff, Heck Tate. The prosecution's attorney, Mr. Gilmer, asks him about the events surrounding Tom Robinson and Mr. Ewell's daughter, Mayella. Mr. Tate states that on November 21, Mr. Ewell came to get him because "some nigger'd raped his girl." He says that he found Mayella on the floor, very beaten up, and that Mayella claimed Tom Robinson had taken advantage of her and beaten her. Atticus questions Tate next, asking whether anyone called a doctor. Mr. Tate says no. Atticus asks where Mayella had been beaten, and Mr. Tate says, with some hesitation, that her right eye and entire right side of her face were bruised, and she had scratches all around her neck.
