Angara, 43, of Holmdel, was last seen on the night of Feb. 8 doing water quality tests at the Passaic Valley Water Commission plant in Totowa, where she worked for 12 years. Divers found her body in a 35-foot-deep sump opening at the bottom of one of the emptied tanks. Investigators are treating Angara’s death as a possible homicide.
