Testimony begins today (Tuesday) in the trial of a man accused in a brutal murder in downtown Madison. Twenty-four-year-old Darrick Anderson is charged with first degree intentional homicide and several misdemeanors, after he allegedly stabbed Andrew Nesbitt more than 70 times in a Madison apartment in March. A motive for the killing has not been disclosed. A jury was selected Monday in Dane County Circuit Court, and testimony is expected for much of the next two weeks.
