Cops Believe They Found Aniah Blanchard's Remains, Stepdaughter of UFC's Walt Harris

Heart-breaking news in the search for Aniah Blanchard ... cops believe they found the 19-year-old's body in a wooded area in Alabama.

Cops have been searching for Aniah ever since she was abducted from a Chevron station on Oct. 23. Blanchard is the step-daughter of UFC fighter Walt Harris.

Days after her disappearance, officials had found Aniah's car, which was covered in blood ... and believed she had suffered a fatal injury during the kidnapping.

Cops hunted down Ibraheem Yazeed -- the prime suspect -- who was seen at the gas station with Blanchard in the moments before her abduction. He was arrested in Florida after leading cops on a pursuit and suffered a busted eye during the apprehension. He's since been charged with 1st-degree kidnapping.

Now, terrible news ... cops say they found human remains in Macon County, Alabama and they believe it's Aniah.

"I can confirm that human remains have been found in Macon County on County Road 2 and we have good reason to believe they are that of Aniah Blanchard," Lee County District Attorney Brandon Hughes said.

Officials say the remains were found in the area between the Chevron Station in Auburn where she went missing and the spot where her car was discovered in Montgomery.

A second suspect in Aniah's disappearance was arrested on Friday -- Antwain "Squirmy" Shamar Fisher -- who's also been charged with 1st-degree kidnapping.
