The 22 year-old woman accused of killing her ex-boyfriend at a Westside post office pleaded not guilty.
Arianne Myles is accused of killing Harold Davis - police say it was a spur-of-the-moment decision.
Davis' father has said the two dated for about a year and a half, and after they'd broken up, Myles had allegedly harassed his son on several occasions.
Myles' next hearing is scheduled for May 1.
