Police recovered a bone Wednesday in Caldwell County that could shed light on what happened to Zahra Baker.
Police wouldn't comment on what kind of bone was found or where in Caldwell County the bone was located.
According to the Hickory Police Department, the bone will be sent to the state Medical Examiner's Office in Chapel Hill for further testing. If the medical examiner's results determine the bone is involved in the case, the bone will be sent to the State Bureau of Investigation for additional testing.
HPD Maj. Clyde Deal said investigators drained two ponds Wednesday near Christie Road in Caldwell County. The ponds, one small and one large, are near the area where investigators located Zahra's prosthetic leg Oct 27.
Officials involved in Zahra's case continue to process evidence obtained during recent searches, but they won't say what that evidence is. They do say, however, that processing the clues doesn't happen overnight.
"It doesn't happen like we see it on TV," Deal said. "It takes time."
Deal said investigators have a long list of clues and leads to follow, and they're doing their best to continue searching for Zahra.
Police are also investigating the validity of letters allegedly written by Elisa Baker, which claim Zahra isn't missing and police know the child's whereabouts.
A website, Serialkillersink.net, claims to possess the letters and is offering them for sale. Deal said police have yet to determine if the letters were, in fact, written by Elisa Baker.
"We'll give that the appropriate consideration, but right now it's on a long list of things, and it's not at the top of the list at this time," Deal said.
Serial Killers Ink claims to sell "murderabilia," which includes letters, artwork and other craft items produced by infamous criminals.
The website appears to have been shut down recently. The site's Facebook page, however, is still functioning and claims, "We at Serial Killers Ink authenticate every item we possess as our stock is obtained by our staff directly from the inmates themselves. We do not buy from private collectors."
The site's owner is Eric Gein, and he claims to have written letters to Elisa Baker while she was incarcerated at Catawba County jail. He also claims he received letters from her, in return.
"We really didn't kill her, but what he did after the fact is kinda horrifying," Elisa Baker allegedly wrote in the letters.
Inmates in Catawba County jail are given paper to write letters, according to Tim Kerley of the Catawba County Detention Facility. Pens are available for purchase.
According to the North Carolina Department of Corrections, jail officials check incoming and outgoing mail for illegal items. Personal letters aren't read unless an officer has reason to believe the letter contains, "threat of harm or physical activity, escape plans or plans to violate prison rules or policies," according to the DOC's website.
Indigent inmates who have no money to purchase stamps receive 10 stamps a month for one-ounce personal correspondence letters.
Elisa Baker remains in Catawba County jail under a $97,200 bond. She is charged with felony obstruction of justice after she allegedly wrote a bogus ransom note found Oct. 9, the day Zahra was reported missing, on the Baker property.
A Catawba County grand jury indicted Elisa Baker on Monday on the obstruction of justice charge. Elisa Baker was scheduled to appear in court Wednesday for a probable cause hearing, but her indictment Monday on the same charge superseded a probable cause hearing, according to the Catawba County Clerk of Court's Office.
Elisa Baker's alleged letters paint a picture of Zahra's father, Adam Baker, as a dangerous man not to be trusted. She allegedly wrote in the letters that she planned to divorce Adam Baker.
When asked if Adam Baker is considered a dangerous man, Deal said, "We have not eliminated anyone at this point in the investigation."
