Neighbor Perleane McDaniel said that Lockard, who lived with his mother and Flippin, was polite and always said hello. But she says she saw Lockard the day before the shooting and was so concerned by his troubled demeanor she almost called the police.
Police have not yet determined a motive.
McDaniel said Lockard worked steadily and was more visible in the neighborhood than his grandfather, who had health problems.
