“…Subsequently to these publications, there have been several manuscripts that highlight the key role of intelligence involving the crime laboratory [45][46][47][48][49][50][51][52][53][54][55][56][57]. While these manuscripts address the role of intelligence in general, other contributions to the literature address the role of intelligence in specific areas of investigation including crime scene investigation [58,59], DNA [60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78], digital evidence [79][80][81][82][83][84][85][86][87][88], document examination [89][90][91], drugs-controlled substances [38,…”

“…Other recent studies on DNA-TPPR include examining prevalence and persistence of DNA or saliva from car drivers and passengers [ [310] , [311] , [312] ], evaluation of DNA from regularly-used knives after a brief use by someone else [ 313 ], studying the accumulation of endogenous and exogenous DNA on hands [ 314 ] and non-self-DNA on the neck [ 315 ], considering the potential of DNA transfer via work gloves [ 316 , 317 ] or during lock picking [ 318 ], and investigating whether DNA can be recovered from illicit drug capsules [ 319 , 320 ] or packaging [ 321 ] to identify those individuals preparing or handling the drugs.…”

“…The authors of one study summarize some key points that could be extended to many other studies as words of caution: “From a wider trace DNA point of view, this study has demonstrated that the person who most recently handled an item may not be the major contributor and someone who handled an item for longer may still not be the major contributor if they remove more DNA than they deposit. The amount of DNA transferred and retained on an item is highly variable between individuals and even within the same individual between replicates” [ 320 ].…”

“…One study in 2008 looked at the probability of obtaining identifiable DNA results from resealable plastic packets in drug-related cases in Norway and the success rate was found to be 14% [18]. Another study looked at the use of Bayesian analysis to evaluate DNA transfer and persistence on resealable plastic packets and rolls of tapes commonly encountered in drug activities [19], while two other studies looked at DNA deposition, transfer, and persistence on the packaging of illicit drug capsules and found the DNA of the person who prepared the capsule [20,21]. In a more recent study that evaluated DNA transfer within a residential setting where the resealable plastic packets (mimicking illicit drug packets) were placed on the surface of the kitchen bench or bedroom drawer, it was found that direct or longer duration of contact led to greater DNA transfer than passive and short duration contact [22].…”
