But the grand jury disbanded with no indictments, and a report simply stating "these types of cases are tough.”
Later that month, a billboard went up on Interstate 40 seeking information about the slayings of Skyla and Taylor, but that has not produced any breaks, either.
Investigators still believe two guns were used to shoot the girls a total of 13 times, indicating there was more than one shooter, and because of the rural location, the shooters likely were from the area.

"I’m really confident that the sheriff’s office and the OSBI want to get it right,” Chancy said. "I just think they don’t want to rush into something and not get a conviction. I’m pretty sure that’s the way most people feel. You don’t want a technicality to prevent a conviction.”
