MADISON, Wis. (AP) -- A former University of Wisconsin-Madison student is expected to plead guilty to fatally stabbing a man during an attempted robbery.
Assistant Public Defender Dennis Burke says Adam Peterson will enter the plea to first-degree intentional homicide on Monday.
Burke says the defense was prepared to concede at the upcoming trial that Peterson killed Marino, but that he should be found guilty of a lesser charge.
Prosecutors say they have tapes of the 20-year-old North Grant, Minnesota man speaking with his parents from jail in which he admits killing Marino during an attempted robbery.
The 31-year-old Marino was stabbed at his Madison home Jan. 28.
Marino was a musician and technical representative for a medical device company.
