NEW YORK AP – A tortuous trial that revealed the elegant philanthropist Brooke Astor as a deluded invalid struggling with Alzheimer’s disease is nearing an end after more than four months of testimony.

Astor’s 85-year-old son, Anthony Marshall, and his lawyer are accused of exploiting the socialite’s declining mental condition to plunder millions of dollars from her estate. Closing arguments are set to begin Monday in Manhattan Supreme Court.
