“… the government notes that it has produced over 3,500 pages of discovery,
which includes expert reports on plant DNA analysis and an extensive timber
valuation analyses. The government expects to call approximately 20
witnesses at trial.”
DNA evidence a big part of the case and potentially influential enough for J&L Tonewoods to
plead guilty
