Two Covington teens and one Newton County man charged with murder appeared in Newton County Superior Court Tuesday for arraignment hearings and entered pleas of "not guilty."

 Cecil Freeman Allen, 19, and Julian Antun Holloway, 18, were charged with the March 10 shooting death of Ashley Obryant Vinson, 20, in the first murder case of the year for the city of Covington.

 Allen and Holloway were charged with four counts of murder, kidnapping, false imprisonment, aggravated assault, violation of the Georgia Controlled Substances Act, five counts of possession of a firearm during the commission of a felony, tampering with evidence and removal of body parts from the scene of death.

 Both pleaded not guilty upon being charged.

 The two teens were allegedly buying marijuana from Vinson, who reportedly knew Holloway from school, in the parking lot of the Magnolia Heights apartment complex when there was a dispute.

 Vinson was shot in the head at close range with a .40 caliber handgun while the three were sitting inside a Buick LeSabre. Holloway and Allen drove back to Holloway's parents' house where they were found by Covington police a short while later with Vinson's body still in the backseat of the car in the garage.

 In an earlier bond hearing, Chief Assistant District Attorney Layla Zon described how everything had been taken out of the car except the body and that the defendants attempted to hide the gun in the attic and flush shell casings down the toilet.

 Allen, Holloway and Crowder remain in custody and are scheduled for a motion status hearing August 12, which will be the last time they would be able to enter a guilty plea in the process towards a trial by jury.

 Also arraigned Tuesday was Darrel Antonio Crowder, 49, charged with fatally shooting his estranged wife, Catcilia Crowder, 43, while their 16-year-old daughter slept in the next room on Jan. 18, in the county's second murder of the year.
