Witness tells of seeing girls before they were shot

Rosser said at an afternoon news briefing that a handful of people have been interviewed and in some cases, polygraph tests were administered.

Investigators are continuing to interview people in connection with the killing of the two girls in rural Okfuskee County, Rosser said. But so far, no arrests have been made and investigators are still trying to determine the motive in the shooting deaths.

Rosser said the information gained didn't add much to the criminal investigation, but did help establish a timeline.

"We're looking for people who may have seen something out of the ordinary," he said.

Investigators have received numerous tips, but many haven't panned out, Rosser said.

Earlier today, the road where the girls were found was blocked off as investigators comb the crime scene again. Agents could be seen using global positioning devices and aircraft was used to survey the area, Rosser said. The road is expected to be closed for much of the afternoon.

In total, 14 investigators are working on the case, he said. Airplanes have also been used to comb the ditch and surrounding fields were the girls were found.

Taylor and Skyla were found shot to death in a ditch along a dirt road less than a mile from Taylor's home Sunday evening. They had gunshot wounds to the head and chest, according to the State Medical Examiner's Office.
