The woman accused of stabbing to death a Dalton convenience store clerk entered a not guilty plea Monday afternoon at her arraignment, the Whitfield County District Attorney said.

Skyy Raven Marie Mims, 21, of Detroit, has been held without bond since her arrest in March, two days after she allegedly killed a 37-year-old store clerk inside the gas station and then helped herself to cash and lottery tickets, according to police.

Dahyabhi Kalidas Chaudhari, known as DK, was working alone on a Sunday night at Kanku's Express on Airport Road in Dalton when he was allegedly approached from behind by a woman who covered his mouth and hit him in the back of the head, The Atlanta Journal-Constitution previously reported. The store's owners said DK, an Indian national, didn't have family in the area, but he was always smiling and quickly made friends with customers.

Mims, an aspiring rapper and model, was identified by surveillance images inside the store, and tips from the public helped investigators track her to a Bartow County home. She was arrested and charged with murder and armed robbery and is being held in the Whitfield County jail. No details about a motive in the case have been released.

In court Monday, Mims’ attorney asked for bond, but the request was denied, DA Bert Poston said in an emailed statement. Mims’ trial, previously scheduled for the week of Oct. 13, has been rescheduled for Nov. 3, Poston said.
