DURHAM, N.C. — In a motion filed Friday, defense attorneys say the accuser in the Duke Lacrosse rape investigation went through at least six sessions with police, trying to point out her attackers.

Defense attorneys for former Duke player Collin Finnerty have requested notes and results from all the line-ups. They say how the accuser identified her alleged attackers is critical to their defense, suggesting there have been discrepancies in the identification process.

Three days after the alleged victim told police she was raped by three lacrosse players at an off-campus house, she was shown a series of pictures of possible suspects. Defense attorney Joe Cheshire claims his client, Dave Evans, was never picked in the first lineup.

Three weeks later, police conducted another lineup with the accuser. During that session, the woman identified Collin Finnerty and Reade Seligmann with 100 percent certainty. She also picked Evans with 90 percent certainty.

Defense attorneys for Finnerty say there were at least six lineups, and possibly even more. They want all the reports and police notes from the sessions

Defense attorneys not related to the case told WRAL it is highly unusual for investigators to conduct so many lineups. Police said they couldn't comment while the case is under investigation.
