A former prosecutor has answered more than six hours of questions from attorneys for a man who says he was wrongfully sent to prison for nearly 25 years because of suppressed evidence in his case.

Ken Anderson gave a deposition behind closed doors Monday at the Williamson County Courthouse in Georgetown, Texas, where he is now a state district judge.

He was questioned by attorneys for Michael Morton, whom DNA evidence freed this month after he spent 24 years of a life sentence in prison in the 1986 murder of his wife.

Anderson's deposition is part of an investigation into allegations that he concealed evidence at Morton's trial while a prosecutor.

An appeals court last week denied his attempt to stop the deposition.
