The cold case of Michelle Parker’s disappearance has a major update.

Nearly 15 years after the then-33-year-old disappeared in Orlando, Fla., police arrested her ex-fiancé Dale Smith Jr. and charged him with second-degree murder, to which he’s pleaded not guilty.

“Smith was the last known person to see or hear from Michelle on Nov. 17, 2011, after she dropped their children off at his home,” the Orlando Police Chief said during an Oct. 14 press conference. “Over the past year, we’ve expanded our investigative team looking into this case and took a fresh-focused look at all of the evidence.”

The chief explained, “We re-examined testimony and conflicting statements made by the suspect and used advances in digital forensics to uncover and analyze additional evidence.”

The same November 2011 day that Parker dropped her and Smith’s 3-year-old twins off with him, the former couple’s episode of People’s Court aired, during which they fought over an engagement ring. Later that night, Parker never arrived for her bartending shift.
