After digging for 25 days, a forensic crew looking for the remains of Jessica Cain, who went missing as a teenager nearly 20 years ago, may finally have a breakthrough.

On Friday, they discovered bones buried four feet underground in a horse pasture along East Orem Drive. The primary suspect in Cain's kidnapping and murder, William Reece, had led police to this field, believing this was where he had buried her in 1997 (he's currently doing 60 years for the kidnapping and rape of a different Texas woman). But for now, it's not clear if the bones are Cain's or if this will open up another homicide investigation — Harris County medical examiners are running a DNA test.

"Right now, we have no clue about the ID," Houston Police Department Homicide Detective Richard Martinez told reporters at the site Friday.
