It was 7:15 in the morning of February 8, 2007. I was walking along Park Road towards the east while an old man came out of the park on the other sides of the street. Then I saw a yellow car drive up Third Street and made a right turn into Park Road. The next moment the car hit the man while she was crossing the road. He fell with a cry. The car didn’t stop and drive off at full speed heading west. I noticed the driver was young woman wore a pair of glasses and the plate number was AC864. After two minutes later, I stopped a passed car and took the old man to the nearest hospital.
