ABUJA, Nigeria --The U.S. Marshals Service says it's aggressively pursuing Jessica Tata and working with authorities in Nigeria to find her. Authorities believe Tata flew to Nigeria two days after a deadly fire at her home daycare. We traveled to Port Harcourt and spoke with people who know Tata's family. Driving around the city is not easy. Walking, questioning and searching are just as difficult. Most people there didn't understand what we were asking. There are many tribal languages that make it difficult to speak with people in different parts of the area. But one thing is clear. The Tata family has dealings in Port Harcourt. Jessica Tata's name is recognized and the accusations she faces cry out louder than ever. "So this is the type of thing that would anger you enough to say Hey, she needs to be found and she needs to be dealt with?" we asked one Nigerian woman. "She's a murderer," the woman responded. Sources tell us Tata's father runs a business there and was responsible for getting her to Port Harcourt and is harboring her there somewhere in a secret location. But according to the U.S. embassy, with which we spoke earlier Friday, they don't have or would confirm that any U.S. official from Harris County or the U.S. Marshal's Office is actually in Nigeria or the village.
