Marie Farrell, a witness in the Ian Bailey case, has at different times named 3 individuals as the man she was with early on the morning of Sophie Toscan du Plantier's murder.
The High Court has heard the Schull shopkeeper told Gardai in 2002 that she saw a man at 3am near the French film producer's home, while with a companion from Longford called Oliver Crochane.
Under cross examination she claims she'd previously given the name Jan Bartells to Gardai on the instructions of a detective.
Last week she said the man with her in the car in 1996 was deceased Longford factory worker, John Reilly, who she denies is an invention.
Former journalist Ian Bailey is suing the State and Garda Commissioner for alleged wrongful arrest.
