Manhattan prosecutors on Thursday started presenting evidence to a grand jury to secure an indictment for the high-profile killing.

Fingerprints belonging to the man charged in last week's murder of UnitedHealthcare's CEO match those found on a water bottle recovered not far from the scene.

Luigi Mangione, the man charged with murder in the death of UnitedHealthcare executive Brian Thompson, has retained a top New York attorney who previously worked in the same office pursuing the case against Mangione.
