Petersburg police identified the victim as Helen Shear, 40, fellow resident and former employer Helen Shear, 40, who used to own B & G Heated Mini Storage, according to the Associated Press.
According to reports, witnesses say Baron shot Shear "without warning" in the business' driveway using a 12-gauge shotgun. Baron then put the weapon to his head and pulled the trigger.
Baron ran the storage facility, which was owned by Shear and her ex-husband, Guy Bartlett, while the couple was out of state. Baron's employment was terminated when the couple returned last spring.
Petersburg Police Chief Dale Stone ruled out robbery or theft as a motive and said drugs or alcohol were ruled out as factors leading up to the murder, according to reports.
