Edited sentence: A shoe print found on the back door and mentioned in a police report, was wiped clean.According to the prosecution theory, Barnes kicked in her back door at 10:30 p.At trial these blood stains were identified as being of Bass’ blood type.Barnes’ mother testified that Barnes arrived home about 11:50 p.Brooks allegedly witnessed this event under bad lighting conditions from 40 yards away while wearing tinted glasses.Brooks initially said he was alone in his car when he saw Barnes.DNA tests later showed that the blood did come from Bass.Given Barnes’ 14EEE shoe size, it easily could have been used to identify or exonerate him.He made this statement before it was known that Bass did not arrive home from work until 11:30 p.His sister, Bobbie Jean Brooks, later said that she was with him in the car.However, coveralls allegedly belonging to Barnes contained only two tiny blood stains.In addition, Brooks barely knew Barnes.She could not formally identify Barnes, but she did say her brother told her that the person they saw was not Barnes.Since the killer was alleged to have worn coveralls in committing the crime, it would seem likely that his coveralls would contain a fair amount of blood spatter.Subsequent to Barnes’ trial, additional witnesses have come forward and have implicated another man as Bass’ murderer.Such a theory seems dubious given Barnes’ relationship with Bass and the fact that Barnes’ mother was picking up Bass from work at 11:15 p.Tests also revealed that the blood contained citric acid, which is a preservative used in stored blood.The medical examiner concluded that the stains did not come from natural bleeding of a normal human being.There were numerous splashes of blood spread widely around the room where Bass’ body was discovered.Thus the bloodstains presumably were planted using a vial of Bass’ stored blood.While driving by in a car, witness Robert Brooks claimed to have seen Barnes, wearing coveralls, hurdle a fence in Bass’ backyard at 10:30 p.and waited an hour for her to return home.that night wearing a tan coat and gray pants rather than coveralls as the prosecution claimed
