Now to our other major story, police say they have detained a man they're calling a strong person of interest in the murder of the CEO of the nation's largest health insurer who was shot in New York City last week, leading to a nearly week-long manhunt that widened beyond the city's limits.

Police said the document they found today revealed more about Mangione, but they provided

few details.
