her body. The acknowledgement, however, indicates that other items were not sent for testing. Results from the supposed tests were never made available, nor was information on why the other items were not sent. According to Carrington, four years after the investigation a detective involved in the case told her that none of the samples taken from suspects were tested. Samples taken from Webster were not used in his prosecution. Professor Harry Boettcher, a forensic scientist, said that if police did not actually test the samples it would be "professional negligence – indefensible". In 2009 a solicitor who acted on behalf of Leigh's family stated that given the advances in DNA testing technology, it was time to re-examine the evidence. Possibility of accomplices Several factors have led to speculation that Webster was not alone when he killed Leigh. According to the transcript of Webster's confession, he was never asked if he acted alone. Carrington accused police of accepting Webster's confession at face value, ignoring both forensic and witness evidence. Her investigations highlighted several discrepancies in Webster's confession, and in the forensic evidence. For example, Webster stated in his confession that he had choked Leigh with his left hand as he knelt beside her although, according to the autopsy report, the bruises on Leigh's neck were consistent with being choked with a right hand. Carrington also questioned Webster's statement that he walked along lit streets to the other side of the Stockton peninsula to wash his bloodstained hands, when he could have washed his hands in total darkness at the beach less than away. She also queried his claim that he had blood on his hands but none on his clothes, despite Leigh having been struck so hard blood was splattered 2.8 metres one way from her body and 1.3 metres the other way. Webster stated that he walked to the beach with Leigh, though according to police reports four witnesses said she walked to the beach alone; two witnesses stated they saw Webster and Wilson leave the surf club together. Neither NC1 nor Wilson had a reliable alibi for their whereabouts at the time of the murder; Wilson told police he was alone on the beach when Leigh walked past him as she left the club, minutes before she was murdered. Webster's statement that he only penetrated Leigh with his finger has been considered by various sources to be inconsistent
