A woman who is 21 weeks pregnant was taken by helicopter to Bayfront Medical Center on Tuesday after her car crashed into a fence on U.S. 19, New Port Richey police said. Jennifer Concannon, 22, was treated for minor injuries and was expected to be released late Tuesday. The accident happened in the northbound lane of U.S. 19, just south of the Pithlachascotee River bridge. Concannon was apparently trying to change lanes to make a right turn when her Pontiac Grand Am was struck from behind by a Toyota pickup truck, police said. The Grand Am slammed into a fence in front of a pool store on U.S. 19. The pickup truck driver, Robert Brown, 26, was treated at North Bay Medical Center and was released. It was not clear whether Concannon or Brown were wearing seat belts. The accident is under investigation.
