Heather A. Stewart, 28, was found dead in her car on the morning of May 30, 2014, in the parking lot of a former Pick n Save on South Church Street in Watertown. A mother of four from Clyman, she worked as a certified nursing assistant for Rogers Memorial Hospital and was reported missing after she failed to arrive for her 11:00 p.m. shift on May 28; she had called to say she would be about ten minutes late but never showed up.

An autopsy determined Stewart died from a gunshot wound to the head and her death was ruled a homicide. Her vehicle was found with the keys in the ignition and still in gear. Investigators focused on 32-year-old Michael Henderson of Waterloo, the father of one of Stewart’s children. Cell phone records placed Henderson in the area, surveillance footage captured his vehicle nearby, and a baseball cap found a short distance from Stewart’s car became part of the evidence. Henderson was arrested in June 2014 and charged with first-degree intentional homicide; a jury convicted him in August 2015. Stewart’s family has worked to create a memorial garden at the site on land donated by the property owner.

Did anyone in the area at the time notice a late-night vehicle or person near South Church Street on May 28–30, 2014?
