WHITFIELD: Hi. Welcome back. Police in Tampa, Florida, are offering a $25,000 reward for information on a series of three sniper-style murders. The bodies were found within a half mile of each other over a ten-day span, making police think they could all be linked. This surveillance footage shows a person walking around the area around the time of the first murder when 22-year-old Benjamin Mitchell was shot at a bus stop October 9th. Four days later, the body of Monica Hoffa was found a few blocks days a way in a vacant lot. The most recent victim is 20-year-old Anthony Naiboa. Anthony, who had autism, was killed Thursday night after riding the wrong bus home from work. Tampa Police are urging people in the area to travel in large groups and be aware of their surroundings. So much more straight ahead in the NEWSROOM, but first, meet this week's CNN hero, a woman spreading literacy to children living in poverty.</s>REBECCA CONSTANTINO, CNN HERO (voice-over): For a child, the library can be a magical place.</s>UNIDENTIFIED FEMALE: I'm officially the most awesome girl in the world.
