Burch. 22, was pronounced dead at her home on Magnolia Drive, in the Wheeling area, on July 30, after a 911 call was placed after the shooting.
According to others at the home at the time of the shooting, Burch and her boyfriend, Brenton Needle, were alone inside the house when the shooting occurred. The two were described as drinking and arguing prior to the shooting.
Burch's body was transported to the State Medical Examiner's office in Little Rock for an autopsy, in hopes the Medical Examiner could determine the manner of death and whether foul play was involved.
Sheriff Foley said additional evidence has been submitted to the state crime lab.
At this time, all of the results are not in and a final ruling has not been made.
Needle of Horseshoe Bend has undergone a polygraph test, however, and no charges have been filed against him in relation to Burch's death.
Needle was recently arrested though, after failing to appear in Fulton County Circuit Court on Aug. 23 on other charges.
Needle, 24, was arrested on March 17, 2011 for Driving While Intoxicated and Use or Possession with the Intent to Use Drug Paraphernalia with the Intent to Manufacture Methamphetamine.
According to a Drug Task Force Affidavit, Needle was stopped after a police officer observed him driving erratically.
The officer detected a stong chemical odor coming from Needle's vehicle and, in a search of the vehicle, officers found materials used in the manufacture of methamphetamine.
According to Foley, Needle was located and arrested after a warrant was issued for Failure to Appear in court. He is being held at the Izard County Detention Center.
