A specially trained dog was brought in Wednesday to re-examine the area along a rural Oklahoma road where two young girls were killed.
Oklahoma State Bureau of Investigation spokeswoman Jessica Brown said the dog is normally assigned to the Bureau of Alcohol, Tobacco, Firearms and Explosives but her handler offered assistance in the weeks-old investigation after returning from out of town.
Brown said the dog's ability to find bullets and casings that were fired years ago or are buried in the dirt helped investigators narrow down some information, although she refused to provide specifics.
Brown said the 3-year-old Labrador Retriever needed only about 45 minutes to search the area near Weleetka where 11-year-old Skyla Whitaker and 13-year-old Taylor Paschal-Placker were found shot to death on June 8.
Investigators believe there may be at least two shooters involved in the killings because each of the girls were shot with two different kinds of bullets.
Brown said the OSBI is still looking for the same potential witness depicted in a sketch released nearly two weeks ago. The man was described as an American Indian, about 6 feet tall, with black hair and a ponytail stretching to the small of his back. Investigators say the man was seen standing near a white Ford or Chevrolet single cab pickup with chrome striping and an Oklahoma license tag around the time and place the girls were shot.
Investigators determined that a woman falsified her story Tuesday claiming that a man matching that description had broken into her house about four miles from Weleetka.
"We want some viable information," Brown said.
