Closing arguments are scheduled for Wednesday in the fourth murder trial of a wealthy New York man accused of killing his estranged wife in 2001.

Calvin Harris is accused of killing 35-year-old Michele Harris, who disappeared the night of the Sept. 11 terrorist attacks. Prosecutors say he killed her when she came home to their Southern Tier estate.

A judge in Schoharie County will hear the arguments, seven weeks after the start of the non-jury trial.

Defense lawyers say authorities overlooked possible suspects she met during the freewheeling life she led as her marriage broke up.

Michele Harris' body has never been found and prosecutors have relied on a largely circumstantial case.

Two previous guilty verdicts against Harris were overturned. A third trial last year ended in a mistrial.
