Freelin Conn filed a voluntary petition under Chapter 7 of the Bankruptcy Code on September 30, 2011. Conn listed Banc- Ohio National Bank as having a claim incurred in October 2010 in the amount of $4,000 secured by a 2003 Oldsmobile. The car is listed as having a market value of $3,500. During the period from June 30, 2011, to September 30, 2011, Conn made three payments totaling $439.17 to BancOhio. May the trustee in bankruptcy set aside those three payments as voidable preferences? Explain.
