Mass Spec Evidence Still Proving a Success – Take a look at our last 6 months!

Mass Spec has supported the police, prosecution and defence in several evidence projects in the first six months of 2015

Mass Spec has supported the police, prosecution and defence in several drugs on money evidence projects in 2015.  Mass Spec experts have presented evidence in court six times this year and have provided evidential statements for 15 others where their attendance was not challenged.  

Whilst the evidence that Mass Spec provides is not the only deciding factor, it is a significant and reliable element that quite often shifts the balance in favour of the party presenting it.  In a great deal of cases, we have not even been asked to attend as the evidence was accepted or guilty pleas put forward. 

One of the more notable cases this year includes the successful prosecution of two men sentenced for Conspiracy to supply of class A in Southampton as reported by the South East Regional Organised Crive Unit.

Another case reported by Dorset police explains how a group of five operating a drug supply operation across Dorset and Liverpool was quashed when drugs and cash were seized after an intelligence operation in Dorset was then traced to operations in Liverpool leading to 5 arrestts. The gang were sentenced to a total of 33 years in prison at Bournemouth Crown Court in May 2015.

Another success was recorded by the Devon and Cornwall police force when a couple were found to be laundering drugs money as reported by the Mirror Newspaper. A couple were flagged to police after bank staff noticed a number of suspicious cash deposits. Upon investigation the couple in question were found to have stashes of cash and class A drugs.

Mass Spec is ready to work with investigating agencies, prosecution and defence councils to produce the most robust evidence possible. Contact us to discuss your needs or challenges and join the many happy customers on our client list.

Designer drug detection variants still detectable

Selling or possessing mephedrone and methylone, also known as "miaow" and "plant food", was made illegal in 2010. Variations on these drugs have surfaced recently but can be detected quickly using Mass Spectrometry

With news that there may be an increase in ‘home-made’ morphine, with the development of a ‘home-brew kit’, Mass Spec has the in-house expertise and equipment to quickly analyse multiple drugs and are always happy to assist with any enquiries as a result of new trends illicit substances.

One of the more recent ‘designer’ drugs Mass Spec has been asked to consider is mephedrone (not to be confused with methadone), which is a cathinone type substance and controlled under the MDA.  Mass Spec validated this new drug quickly and efficiently when it emerged a few years ago and has since assisted in many court cases involving illegal use and distribution of the substance (drug).

If you have any types of drugs or cutting agents that you may wish us to analyse for you, please contact us for our expert opinion and quotation.  We already have a multitude of compounds validated on our systems and ready to go!

Guilty or Not Guilty?

Dr. Richard Sleeman, Scientific Director weighs-up the odds that likelihood ratio's are here to stay.

When evaluating evidence for use in a court of law, evidential data are presented together with two competing propositions which may account for this data: one from the prosecution and one from the defence. The aim of the court is to evaluate which of the two propositions is more likely. In other words, is the probability of the prosecution hypothesis given the evidence bigger than the probability of the defence hypothesis given the evidence?

We want to know whether the ratio of these probabilities is greater than one (overall support for the prosecution hypothesis), or less than one (support for the defence).

This ratio is known as the Likelihood Ratio and it is meant to represent  the odds before seeing any evidence to the odds taking the evidence into account.

What is the theory and models behind this approach? Dr. Richard Sleeman explains further in the attached paper from March 2015 issue of Mass Matters Magazine.

Plastic banknotes won't foil justice

What does the introduction of plastic banknotes mean for trace detection of illicit drugs on money evidence?

As the introduction of plastic banknotes in Scotland has begun, England awaits the much anticipated polymer £5 note in 2016. The new bank notes are said to last 2.5 times longer and are cleaner than the paper banknotes used today.

Cleaner? What does that mean for trace detection of illicit drugs and other substances on banknotes in the future?

Mass Spec researchers are already preparing for the changes working with the Bank of England to ensure the transition from paper to plastic as smooth as possible.  We are determined to take such changes in our stride and continue with the excellent reputation we have earned helping the justice system by analysing banknotes and other items for traces of drugs.

The first challenge we have is the plastic polymer material itself. The thermal desorber that we use today for paper banknotes will be adapted for the new material and tests run to date have been successful.

One of the attractions of polymer money is that it collects fewer bacteria than paper banknotes and can even be ‘cleaned.’ A study by the University of Ballarat in Australia found that there were usually fewer bacteria on polymer bills than cotton-based ones – a health bonus for all!

However for Mass Spec, we’re not looking for bacteria but rather particles of illicit substances that link the money to drug related activities. The contact of the banknotes to the particles in question is normally a short time before they are seized; thereby eliminating any chance of the money being ‘cleaned’. In addition, large volumes of cash are inevitably going to be difficult to fully clean quickly and effectively, enabling our analysis to stand strong with many different cash seizures. Mass Spec’s tests are proving that our methods of detecting traces of substances on polymer banknotes is just as effective as those that we use on paper banknotes today.

Cocaine and Sandwiches

The BBC Points West news programme visited the Bristol-based offices of Mass Spec and shot an interview piece with Dr. Richard Sleeman where he explained that virtually all bank notes in circulation have traces of illicit drugs, including cocaine, on them.

The recent story about a Bristol bus driver who was found to be unfairly dismissed after testing positive for cocaine during a random drugs tests caught the imagination of the press in the west of England and the UK national news as well. The bus driver claimed that cocaine from hundreds of bank notes that he had handled during the day had transferred to his hands and then onto his sandwiches; explaining why after lunch, he tested positive for cocaine after being given a saliva test.

The BBC wanted to add an expert opinion to their coverage of the story and contacted Mass Spec to share our experience with drug – specifically cocaine – presence on bank notes.

The BBC Points West news programme visited the Bristol-based offices of Mass Spec and shot an interview piece with Dr. Richard Sleeman where he explained that virtually all bank notes in circulation have traces of illicit drugs, including cocaine, on them. Cocaine, he explained, is particularly pervasive because it is such a stable compound and does not break down as quickly as many other illicit drugs found on banknotes.  Of course, with one of the largest drugs-on-money databases in the world with more than 120,000 banknotes analysed from over 170 locations across the UK, Mass Spec can speak with authority on the topic!

The insight proved very useful in providing a scientific perspective backed by real-world experience and led the BBC to feature Dr Sleeman on the BBC Radio 2 Jeremy Vine show, BBC Bristol Radio with Geoff Twentyman and BBC Points West Television news.

Rapid Analysis of Drugs and Explosives

Canadian Border Services Agency publishes paper advocating novel approach.

Government agencies across the globe continuously evaluate security equipment, which is employed in Drugs and Explosives detection applications. Security equipment can be broadly divided into two categories: ‘bulk’ detectors such as metal detectors or X-Ray scanners, which rely on the presence of a significant amount of a material; and ‘trace’ detectors, such as ‘sniffer’ systems, which detect the presence of minute quantities of a threat material which may remain after handling illicit materials.

Trace detectors are used for explosives detection at locations such as airports, stadia or public buildings, and for drugs detection at ports of entry or in nightclubs. Whether the need be for the detection of drugs, explosives or even chemical warfare agents, the authorities must determine the efficacy of the various solutions proposed to address terrorist or criminal threats. To do this, governments must undertake tests to determine the limit of detection of the equipment proposed to a range of target analytes.

Recent work by Tam et al of the Canada Border Services Agency (CBSA) has advocated the use of the ‘Scentinel’ system to massively reduce the time required to obtain results. Government bodies like the CBSA regularly conduct hundreds of experiments to understand the performance of the expanding number of trace detectors available commercially. New iterations of existing designs, not to mention urgent requirements to study new drugs or explosives that may come to light, exacerbate the number of experiments required.

The CBSA paper concluded that the Scentinel system desorber is highly efficient for a range of explosives, and that the results it produces are quantitative (i.e. the instrument response is directly proportional to the amount of explosive present). The CBSA confirmed that the analysis undertaken by the Scentinel takes a few minutes compared to the many hours required for conventional analysis and that no sample pre-treatment is required (no solvents, no derivatisation, or filtration).

Mass Spec Analytical Scentinel SystemThe Scentinel is designed and manufactured by Bristol based Mass Spec Analytical Ltd. The instrument is based on an ABSciex triple quadrupole tandem mass spectrometer, which has been modified to incorporate a thermal desorption sample inlet system. The device simply heats samples to evaporate the compounds of interest, and draws the vapour into the mass spectrometer for analysis.

Rapid Analysis of Drugs and Explosives

A significant, longstanding figure within the drug dealing fraternity in Scotland has recently been found guilty by a majority verdict.

Mass Spec's experts were engaged by Police in Scotland to analyse quantities of cash seized from the defendant, which were subsequently found to be unusually contaminated with diamorphine, or heroin. Thereby supporting the proposition that the banknotes were involved in a drugs related activity such as supply of heroin.

The defendant, who was a major Police target, now faces a lengthy prison sentence, having been jailed for five years and five months after being convicted of drug dealing in Edinburgh.

His co-defendant was sentenced to four years three months, after earlier pleading guilty to being concerned in the supply of heroin
