Nichols was found guilty May 26 of 161 counts of first-degree murder for 160 victims and an unborn child in a state trial.
Nichols is a felon.
If he were convicted of killing 160 victims, he is obviously a felon.  Since felon isn't mentioned in the context, the AI doesn't seem capable of being able to infer that.
