George Kendley — he served as the 172nd witness to provide testimony.

George Kendley, witness for the State in rebuttal, at the Trial of Leo Frank in the Fulton County Superior Court of Atlanta, Georgia, in 1913 (Testimony Portion From July 28 - August 21, 1913; Closing Arguments August 21-25, 1913)
Streetcar conductor George Kendley testified that on April 26, 1913, he saw Mary Phagan step off the viaduct at Marietta Street around noon, walking toward the pencil factory. He was on the front end of the Hapeville car, scheduled to arrive at 12:00 p.m.
On cross-examination, Kendley admitted he did not know if his car was on time that day. He told several people the next day that he saw her, estimating her arrival around 12:10 p.m. if she left home at 11:50 a.m. He could not swear the sighting was exactly on the minute—only that it was before 12:05 p.m. and his car was on schedule.
Kendley denied:

vilifying Frank on streetcars,
telling T. Y. Brent that Frank’s “children said he was guilty,”
threatening to join a lynch mob if Frank were released (though he recalled someone saying “there might be trouble”).

He acknowledged discussing the case with Mr. Leach and Brent, but insisted Brent initiated conversations. Kendley did not testify at the coroner’s inquest because no one asked him.
This testimony aimed to place Mary Phagan near the factory at noon, but cross-examination exposed its vagueness, reliance on memory triggered by news, and Kendley’s prior inflammatory statements—undermining both his precision and impartiality.
