Christopher Floyd Boder In executing the warrant, police seized an empty rifle case and ammunition that was said to match a spent cartridge located near Nelson's body. Peterson's attorney, Matthew Benfield, asked the court in December to schedule a hearing, at which police officers and other witnesses could be called to testify about the basis for the warrant. Evidence could be suppressed if there was a finding of false statements or omissions that led to the search. Benfield's motion attacked the credibility of the state's key witness, Jamie Sanford, who provided a detailed account of the events leading up to Nelson's death. He also cited an apparent inaccuracy in describing one witness' location, along with omitted statements from others in the neighborhood, in claiming that there was evidence of an "alternate suspect."
