The Lady In Black Veils (Updated)

It was a bright and sunny day. The clouds were rather sporadic. Cars were whizzing by. Students from the nearby colleges were walking down the five foot alleys. Some were chatting, some were pacing themselves out to get somewhere, a bunch of them were smoking as well. It was business as usual for everybody. And at the side of the road, there was this lady. In her hands, there were two plastic bags. One bright red and the other, green. She had just returned from shopping at the nearby market. Well, this lady, she, wanted to cross the road to get to the bus stop. A road which was wide enough to fit two cars. But as simple as this task might seem, she could not do it. You see, this lady was not a young lady but rather a frail old woman. She was blind on both eyes and had to rely on her walking stick and her ears to help her to walk. And to make matters worse, she had to carry two heavy plastic bags as well as to rush home to feed her ailing niece with the medicine which she had just purchased at the pharmacy. This made her life a whole lot harder and a whole lot more dangerous. Because, every time she tried to cross the road, cars would simply zoom by her, not willing to stop and spare a moment at this old lady. Once, she had almost gotten to the middle of the street but she was forced back to the side of the road by an angry motorist who started honing at her while bombarding her with all kinds of unpleasant words without any regard for this old lady's feelings. Though she couldn't see his face, she could vividly imagine the anger on that motorist's face. At this point, she was heartbroken . And even though many people witnessed this event, no one, no one stepped forward o help this poor old lady. Everybody merely watched the drama and then walked away. Was it her fault that she couldn't walk fast? Was it her fault that she is blind? Was it her fault that she is a frail old lady who had to rush home to care for her sick niece? Was she accountable for all these things? This was not the first time which she had been treated like this. Even in the market, traders took advantage of her disability to cheat her of her money, commuters never making way for her to sit in the bus, insolent young kids made fun of her and mothers telling their kids what they would become if they didn't eat their vegetables. It was all too much for her to bear. But yet, she soldiered on with a brave heart. Upon thinking of this, she became so sad that she had started to sob silently. Tears came trickling down her aging cheeks. She wasn't sad because she couldn't cross the road or that no one would help her to do it, but she was sad because she knew that the longer she took to cross the road, the longer her niece would suffer from her fever. Her niece of only 6.
Then, when all hope seemed lost, suddenly, she was gently tapped on the shoulders by a young college student. He offered her a handkerchief and some kind words to calm the old lady down. Then, upon doing that, he walked up to the middle of the street and raised his arm towards the oncoming motorists, signalling them to stop. His friend on the other hand helped the old lady to walk across the street. He didn't rush her, but instead, she took her step by step across the road. And no matter how loud the protests of the impatient motorists, the young college boy never wavered, he continued to stand in the middle of the road until his friend had safely walked the old lady to safety.
Then, upon, reaching the other side of the street, the old lady was reduced to tears. She wanted to thank these two young souls but she couldn't because she was overwhelmed by her emotions. These two young souls immediately comforted the old lady, wiping away her tears while showering her with kind words. Many of the friends of these two young college students passed all kinds of unkind remarks to them because they helped this old lady. An act which was considered "un cool". But despite the name calling, they still gave their undivided attention to this old lady. The old lady was extremely happy. She was overwhelmed by kindness which she had just received from the two souls who had helped her. Then, once this old lady had stopped crying, the boy asked her where she had wanted to go. The old lady then told him where she had wanted to return to her house to take care of her ailing daughter. And without hesitation, upon realizing how scarce the buses were and the urgency of the situation, the girl offered to drive the old lady to her home. At first, the old lady refused, but she was kindly persuaded into accepting the offer.
The next day, in the news headlines, "The Body Of Old Lady Found Sprawled In Kitchen"
In the report, the journalist stated that according to police, along with the body of the old lady, investigators found the body of a young girl in one of the bedrooms , who was later identified from personal documents as her niece. The young girl had been stabbed repeatedly with what investigators believed to be a knife. There were no signs of forced entry, neither were there signs of a struggle, robbery or sexual assault. Eye witnesses related to investigators that earlier that morning, the old lady. was seen alighting from a red car. And according to them, two male teenagers, were seen helping the old lady into her house. They then heard a loud crash followed by a long period of silence. A few minutes later, they saw the teenagers driving off in the red car. But the odd thing was, a few minutes later, through an open window, a neighbour saw a lady in black veils walking slowly down the staircase into the living room. At that time, none of them thought anything about that unusual occurrence. The police have since mounted a manhunt for the two teenage suspects. The names of the deceased have been withheld pending notification of their respective families. The question is, who did it and why?
