Investigators are looking into new leads and returning to the scene where two girls were murdered less than two weeks ago. The Bureau of Alcohol, Tobacco and Firearms is helping. They have volunteered one of their dogs to help in the search for the killer.

Officials will head out to the murder scene near Weleetka in Okfuskee County. Skyla Whittaker and Taylor Paschal-Placker had gone for a walk when they were shot to death.

Police say two weapons were used in the girls' killings.

Investigators will use the dog specially trained to detect anything using gunpowder, like bullet casings. The dog and his handler will meet with Oklahoma State Bureau of Investigation workers.

While they are searching, other agents will track down information on a stack of leads they have gathered so far in the case. They're still in search of a person of interest in the case. A composite sketch of the man was released in the days after the crime.

People in Weleetka have chipped in on a 30-thousand dollar reward fund for information leading to an arrest in the case.
