Tracking a Killer I (15x24)

:

Early each morning, local fishing constable Tony Jackett patrols the waterways around tiny Truro, Mass., on the tip of Cape Cod. Jackett, who comes from a long line of Portuguese fishermen, has been married nearly 30 years. At 52, he has five grown children and is already a grandfather. He should be enjoying this time of his life. But lately that's been impossible. What happened here on Jan. 6, 2002, changed not only Jackett's life, but the town of Truro as well. In January 2002, Christa Worthington, a glamorous former fashion writer, was murdered in her home, stabbed in the chest. Correspondent Susan Spencer updates a mysterious murder case that was reported on Aug. 5. 2002.
