The fascinating field of forensic science can be challenging to understand. Written for non-scientists, or those with limited scientific knowledge, this book covers the three main areas of an investigation where forensic science is practised: at the scene of the crime, in the forensic laboratory and at court. The fourth edition of this popular book features a new chapter on identifying an individual, including biometrics and a new chapter covering digital crime. The book has been updated throughout, keeping readers at the forefront of current practices across the forensic disciplines. Ideal for anyone studying forensic science or law, this book details how crime scene and forensic examinations are conducted in the United Kingdom, courtroom procedures and the role of the expert witness. It is an excellent source of information for anyone with a role in an investigation, including the police and crime scene investigators.

Many search and recovery operations for human skeletal remains are unsuccessful due to difficulties recognizing bones in outdoor environments even when evidence indicates the last known whereabouts of missing individuals. Though the collagen component of bone is known to emit fluorescence, this property has not been leveraged consistently during skeletal remains searches. Thirty‐six mock searches were completed in 5000 ft2 zones of eastern deciduous forest by volunteers associated with the Virginia Department of Emergency Management. Pig and deer bones were scattered and partially concealed under brush and leaf cover. Pairs of volunteers were allowed up to 1 h to conduct searches in their usual pattern. Nighttime searches were conducted with handheld alternate light source (ALS) devices (uvBeast™, Crime‐lite®, ForenScope, and Labino AB), which produced ultraviolet (385–395 nm), violet (395–425 nm), blue (~455 nm), cyan (~510 nm), or green (~530 nm) lights. Filtered safety glasses were paired with appropriate ALS. Daytime searches were conducted under the same parameters, without ALS. Results indicated that (1) nighttime searches with ALS produced a recovery rate more than triple that of daytime searches (p < 0.0001) and that they were often completed more quickly, and (2) the violet Crime‐lite®, due to breadth of illumination and strength of fluorescent response, consistently produced the highest recovery rate (95%). Data suggest that nighttime searches with ALS can be used both as the primary search method for locating and recovering human skeletal remains, and as a secondary method for recovering any bones expected to be present but not found during daylight searches.
Excavations at the Pre-Pottery Neolithic B ritual site of Naḥal Roded 110 in the Southern Negev, Israel, have revealed evidence—unique to this region—for on-site flint knapping and abundant raptor remains.
