Problem:Meredith Kercher crime scene investigators joked about taking cocaine to stay awake 
  
 They laughed while searching blood-spattered bedroom 
  
 Officers forgot to bring vital equipment 
  
 Damning dossier of 50 police blunders 
  
  
  
 Forensic officers searching the bedroom of murdered British student Meredith Kercher were heard joking about taking cocaine to stay awake, it emerged today. 
  
 The two unidentified Italian CSI investigators are seen in the official video shown to the court during the appeal in Perugia of Amanda Knox and Raffaele Sollecito. 
  
 One of the men is heard to say: 'I could really do with some cocaine to give me a kick.' 
  
 Investigation: Forensic police - not the officers filmed on the official video - outside the house in Perugia where student Meredith Kercher was found murdered 
  
 His colleague replies: 'Don't you mean crack?' Both then laugh loudly while examining the blood-splattered room. 
  
 In other parts of the film they seem to be confused over which equipment to use to examine the scene and one then reveals how a product known as Luminol which shows up blood invisible to the naked eye has been left in Rome. 
  
 Murder victim: British student Meredith Kercher 
  
 The revelations will bring fresh heartache for the Kercher family who after last week's dramatic acquittal of Knox, 24, and 27-year-old Sollecito are left wondering just who killed their daughter. 
  
 She was found semi naked and with her throat cut at the house she shared with American student Knox. 
  
  
  
 During the appeal, the court heard from two forensic professors who were appointed by judge Claudio Pratillo Hellman to look into the way the investigation was handled and they produced a damning report. 
  
 Professors Carla Vecchiotti and Stefano Conti said they had counted more than 50 errors police made as they examined the murder scene and their report was vital to the acquittal of Knox and Sollecito. 
  
 Key to the original conviction in December 2009 had been a 30cm kitchen knife recovered at Sollecito's apartment and on which was found DNA from Meredith on the blade and that of Knox on the handle. 
  
 However the court was told by the experts the amount from Meredith was so low it should not be used as evidence because it could not even be retested - although the DNA on the handle was confirmed as Knox's. 
  
 Sollecito was convicted because his DNA was found on a clasp from Meredith's bloodied bra but the experts revealed that it was collected six weeks after the murder making the possibility of contamination highly possible. 
  
 Murder scene: The house which Meredith Kercher shared with Amanda Knox. The police forensic team made 50 blunders searching the property 
  
 The experts also pointed out how simple breaches of protocol when gathering evidence had been made including using dirty gloves, not covering hair and not changing shoe covers as well as putting items in plastic bags instead of paper ones. 
  
 This coupled with the 'jovial unprofessional manner' of the forensic team opened up serious questions over the reliability of the police investigation - although they insist all standards and regulations were followed. 
  
 Today no-one was available to comment on the joke made by the officers at the forensic unit HQ in Rome, but Patrizia Stefanoni who led the probe repeatedly told the court the investigation had followed procedures and criticism was unfounded.

 Luciano Garofalo, a former commander of Italy's leading forensic investigation unit with the carabinieri paramilitary police said:"You have to remember that these scenes of crime probes last hours and hours - we are not robots, we are humans. 
  
 "The work of the scientific unit has been criminalised over the last few weeks, they were just having a laugh and letting off steam. 
  
 'I would like to put anyone in that situation and see how they cope, see if they don't make a joke. 
  
 "The finds were reliable and at the end of the day its only these two so- called experts who have this theory which has not been double checked. 
  
  
  
 'Are they experienced enough ? Are they up to the standards of the forensic police? ' 
  
  
  
 Acquitted: Amanda Knox and her then boyfriend Raffaele Sollecito outside the home she shared with Meredith Kercher 
  
 Last night neither of Knox's lawyers Carlo Dalla Vedova and Luciano Ghirga were available, but a member of the defence team said: 'This is why we asked for an independent report. We were just not happy with the methods used.' 
  
 Meanwhile, it has also emerged that Knox intends to sue Italian police for wrongful arrest and imprisonment - but she will have to wait a year until the Supreme Court in Rome makes a final judgment on the case. 
  
 They are will rule late next year on whether the appeal should be upheld or overturned and the trial reopened. 
  
 Meredith, from Coulsdon, was in Perugia as part of her Leeds University European Studies degree and had only been in Italy for two months before she was murdered. 
  
  
  
 Knox and Sollecito were convicted sentenced to 26 and 25 years respectively. A third defendant, Ivorian drifter Rudy Hermann Guede, 24, was also convicted and had his 16-year prison sentence upheld by Italy's highest court.

 She was released from prison only to land in the hot spotlight of the media, but Amanda Knox is finding ways to feel free."Amanda did manage even to go out one evening 'undercover,'" her father Curt Knox tells PEOPLE. "Soon, she was recognized by the managers of the establishment who told her not to worry that they wouldn't tell anyone, and to just get on and enjoy her evening."Other nights are spent quietly at home, Knox says of his daughter, 24, who was tried and convicted of the 2007 murder of her roommate Meredith Kercher in Perugia, Italy, before being released from prison Oct. 3 after a successful appeal."Amanda spent the evening at my house … with her half-sisters Delaney, Ashley and her sister," he says. "We all had Chinese takeaway."When she first returned to U.S. soil, though, there was jubilation and a full-on reunion in her hometown of Seattle, Wash."On the first evening back, we held a welcome back party for Amanda with the family and her friends," Curt says. "She saw her grandmother whom she has missed so much, she saw her two little cousins who were toddlers when she left for Perugia."Curt says his daughter happily reunited with a former boyfriend at the party."We had also invited some of her friends along, even the boy she split up from before leaving for Perugia," Curt says. "They spent some time chatting, but I don't think there is room in these days in Amanda's head for romance. For her he is just a dear friend."He says Amanda also hopes to reconnect with her Italian boyfriend and fellow defendant, Raffaele Sollecito, 27, who was also released on appeal."We have told Raffaele Sollecito and his family to come over and visit if they feel like it," Curt Knox says. "I am pretty sure he will come over soon."For more on Amanda Knox, including details of her prison ordeal, pick up PEOPLE on newsstands now |||||
Solution:
During Amanda Knox’s appeal, forensic professors testified that police made more than 50 errors while examining Meredith Kercher’s murder scene, from using dirty gloves to not changing their shoe covers. They also exhibited a “jovial unprofessional manner”—namely, they joked about taking drugs to stay awake, the Daily Mail reports. In official video shown to the court, one forensic officer says, “I could really do with some cocaine to give me a kick.” Another replies, “Don’t you mean crack?” and both laugh. The crime scene investigators also appear to be confused at times over what equipment to use. But one former forensic investigation commander justified their behavior, noting that the probe took “hours and hours” and the officers were “just having a laugh and letting off steam.” Meanwhile, back in Seattle, Knox is continuing to celebrate her newfound freedom. In recent days she’s enjoyed takeout Chinese with her family, reunited with an ex-boyfriend, and even gone out on the town one night “undercover,” her father tells People.
