The Oneida County woman convicted of poisoning and killing her boss has lost her appeal.
A New York State Appellate Court issued the ruling in Kaitlyn Conley's appeal Friday. Conley is serving 23 years for first-degree manslaughter for the death of Mary Yoder.
The appeal focused on a manslaughter charge added during her second trial; it was not part of her indictment.
The prosecution claimed the amount of colchicine given to Yoder showed there was intent to kill, rather than just make her sick. The defense argued the lesser charge was just a way to get a verdict, noting the first trial's hung jury and the lack of a murder conviction in the second.
