Mark Ivan Weekly, 50, of Lakeland, Florida, was murdered on July 18, 2015. His body and that of his six-year-old granddaughter, Meredith Jessie, were found in plastic storage bins behind a neighbor’s shed; both had been stabbed and shot multiple times.

Cheyanne Jessie, Weekly’s daughter and Meredith’s mother, reported them missing and initially said Weekly had taken Meredith to Georgia. Investigators uncovered evidence that Jessie had killed both during a confrontation. Jessie later confessed, telling authorities she acted in self-defense against her father and that Meredith was accidentally stabbed during the struggle. Prosecutors argued the killings were premeditated and motivated by Jessie’s desire to appease a boyfriend who had threatened to leave over Meredith’s behavior.

Jessie was charged with two counts of first-degree murder. At trial the prosecution introduced evidence about her mental health history, including major depressive disorder and psychological deficits; the jury convicted her and she received life imprisonment without parole. Does anyone have information about Mark or Meredith’s lives in Lakeland that could shed light on what led up to July 18, 2015?
