Franklin County Coroner Brad Lewis said Kasler was lying in a position where his diaphragm was prevented from contracting.
Lewis said it's not clear why the 45-year-old man couldn't push himself through the first-floor window or how long he had been hanging there before he died Friday.
The neighborhood is a high-crime area and police said a passer-by told them she didn't stop to help because she thought Kasler was a burglar. Someone else called police after realizing that Kasler wasn't moving.
