MADISON, Wis. (AP) — Madison police believe a Cross Plains man has information that could help them solve the 2008 slaying of a University of Wisconsin-Madison student. But, that man, Andrew Scoles, says he wants two felony convictions expunged from his criminal record before he'll give investigators more information about his friend and former roommate, who he says has confessed to killing Brittany Zimmermann.

The State Journal (http://bit.ly/2aFOIem ) reports the 38-year-old Scoles says he wants a 2010 marijuana possession conviction in Green County and a 2014 federal conviction for possession of firearms as a felon expunged so he can get his gun collection back. It was confiscated by police. The federal conviction would require a presidential pardon.

Scoles appeared in Dane County Circuit Court Thursday on an additional charge of possessing a gun as a felon.
