Dr. Henry Lee testified over four days in August 1995 as a defense forensic expert, undergoing direct examination by Barry Scheck and cross-examination by prosecutor Hank Goldberg about bloodstain and imprint evidence, crime-scene procedures, and evidence collection. Lee testified that wet-transfer patterns on Item 47 did not add up and said “something is wrong,” while acknowledging that he did not know how the transfer occurred or who placed the swatch in the bindle; he also discussed walkway imprints and evidence that he said could indicate a second person was present. Goldberg's cross-examination elicited concessions about possible sources of walkway prints and limits in Lee's documentation, and Lee later testified in the 1997 civil trial about crime-scene photographs, blood evidence, and sock-transfer patterns.
