BBC Two cameras follow serious crime investigations in real time, revealing the crucial role cutting-edge forensic science now plays in bringing criminals to justice. In the first episode of the documentary series, titled "The Harvest", detectives in Newcastle must identify a gunman from evidence left at a shooting scene on a quiet housing estate where Crime Scene Manager Alan Sayers makes it his mission to oversee the gathering of evidence before it's compromised or destroyed by neighbours, passers-by and other members of the public. On the other side of the city, a father who is paying a visit to his son discovers him dead and his flat covered in blood, leading Kathryn Bolam and her team of detectives enlist the help of pathologist Nigel Cooper to determine the cause of death of the victim. Is this a case of a particularly gruesome suicide or are Kathryn's gut instincts right and are there more sinister forces at work? Forensics: The Real CSI - Wednesday 9:00pm on BBC Two.
