Abstract
Recovery of suitable amounts of quality DNA from copper and brass surfaces, like those encountered in ammunition, has been a challenge for the forensic community. The ability of copper ions to rapidly facilitate oxidative damage leading to fragmentation of DNA significantly reduces the pool of templates for PCR amplification. We compared two methods for recovering mitochondrial (mt) DNA from the surface of unfired copper projectiles, brass casings, and aluminum casings, and found that using a cotton swab moistened with 0.5M EDTA was the favored approach, especially when the metallic surface was etched. Degradation was significantly higher for DNA samples recovered from copper and brass surfaces, when compared to aluminum. Massively parallel sequencing (MPS) of the control region, using the PowerSeq™ CRM Nested System kit and the Illumina MiSeq instrument, produced full haplotypes for aluminum samples regardless of the method used to deposit or collect DNA, while less than 60% of the copper and brass samples produced partial or full profile information. Touch DNA collected from copper and brass samples produced higher rates of partial or full MPS profile information (∼88-96%), while collection with 0.5M EDTA produced better results than when collection was performed with water; average of ∼70% versus ∼47%. While MPS data was not impacted by noise in the sequencing process, a higher than expected rate of noise was observed, potentially due to an increase in low-level damage lesions. Noise patterns were strikingly different when compared to control data, suggesting that noisy sites may be predictable when testing samples with high levels of oxidative damage. Library preparation was a poor predictor of MPS data quality, as a large percentage of reads did not align with the reference genome. This may impact the number of samples that can be run when a deep-coverage MPS approach is being considered for analysis of mtDNA heteroplasmy. Overall, when applying an MPS approach to the analysis of mtDNA recovered from ammunition, results are expected from touch DNA, will be limited for copper and brass components when the DNA is exposed to an aqueous environment, and DNA degradation will be accelerated when DNA comes in contact with copper or brass surfaces. Practitioners should consider collecting DNA from metallic surfaces with 0.5M EDTA, as this will maximize yield and mitigate degradation. The results of this study directly impact MPS analysis of minor mtDNA sequence variants from metallic surfaces, and are particularly relevant to forensic investigations.

Abstract
The transfer of mitochondrial genetic material into the nuclear genomes of eukaryotes is a well-established phenomenon that has been previously limited to the study of static reference genomes. The recent advancement of high throughput sequencing has enabled an expanded exploration into the diversity of polymorphic nuclear mitochondrial insertions (NumtS) within human populations. We have developed an approach to discover and genotype novel Numt insertions using whole genome, paired-end sequencing data. We have applied this method to a thousand individuals in 20 populations from the 1000 Genomes Project and other datasets and identified 141 new sites of Numt insertions, extending our current knowledge of existing NumtS by almost 20%. We find that recent Numt insertions are derived from throughout the mitochondrial genome, including the D-loop, and have integration biases that differ in some respects from previous studies on older, fixed NumtS in the reference genome. We determined the complete inserted sequence for a subset of these events and have identified a number of nearly full-length mitochondrial genome insertions into nuclear chromosomes. We further define their age and origin of insertion and present an analysis of their potential impact to ongoing studies of mitochondrial heteroplasmy and disease.

Abstract
Genetic markers, defined as variable regions of DNA, can be utilized for distinguishing individuals or populations. As long as markers are independent, it is easy to combine the information they provide. For nonrecombinant sequences like mtDNA, choosing the right set of markers for forensic applications can be difficult and requires careful consideration. In particular, one wants to maximize the utility of the markers. Until now, this has mainly been done by hand. We propose an algorithm that finds the most informative subset of a set of markers. The algorithm uses a depth first search combined with a branch-and-bound approach. Since the worst case complexity is exponential, we also propose some data-reduction techniques and a heuristic. We implemented the algorithm and applied it to two forensic caseworks using mitochondrial DNA, which resulted in marker sets with significantly improved haplotypic diversity compared to previous suggestions. Additionally, we evaluated the quality of the estimation with an artificial dataset of mtDNA. The heuristic is shown to provide extensive speedup at little cost in accuracy.

Abstract
Determining the host preference of vector ticks is vital to elucidating the eco-epidemiology of the diseases they spread. Detachment of ticks from captured hosts can provide evidence of feeding on those host species, but only for those species that are feasible to capture. Recently developed, highly sensitive molecular assays show great promise in allowing host selection to be determined from minute traces of host DNA that persist in recently molted ticks. Using methods developed in Europe as a starting-point, we designed 12S rDNA mitochondrial gene probes suitable for use in a reverse line blot (RLB) assay of ticks feeding on common host species in the eastern United States. This is the first study to use the 12S mitochondrial gene in a RLB bloodmeal assay in North America. The assay combines conventional PCR with a biotin-labeled primer and reverse line blots that can be stripped and rehybridized up to 20 times, making the method less expensive and more straightforward to interpret than previous methods of tick bloodmeal identification. Probes were designed that target the species, genus, genus group, family, order, or class of eight reptile, 13 birds, and 32 mammal hosts. After optimization, the RLB assay correctly identified the current hostspecies for 99% of ticks [Amblyomma americanum (L.) and eight other ixodid tick species] collected directly from known hosts. The method identified previous-host DNA for approximately half of all questing ticks assayed. Multiple bloodmeal determinations were obtained in some instances from feeding and questing ticks; this pattern is consistent with previous RLB studies but requires further investigation. Development of this probe library, suitable for eastern U.S. ecosystems, opens new avenues for eco-epidemiological investigations of this region's tick-host systems.

Abstract
Exploring technological limits is a common practice in forensic DNA research. Reliable genetic profiling based on only a few cells isolated from trace material retrieved from a crime scene is nowadays more and more the rule rather than the exception. On many crime scenes, cartridges, bullets, and casings (jointly abbreviated as CBCs) are regularly found, and even after firing, these potentially carry trace amounts of biological material. Since 2003, the Forensic Laboratory for DNA Research is routinely involved in the forensic investigation of CBCs in the Netherlands. Reliable DNA profiles were frequently obtained from CBCs and used to match suspects, victims, or other crime scene-related DNA traces. In this paper, we describe the sensitive method developed by us to extract DNA from CBCs. Using PCR-based genotyping of autosomal short tandem repeats, we were able to obtain reliable and reproducible DNA profiles in 163 out of 616 criminal cases (26.5%) and in 283 out of 4,085 individual CBC items (6.9%) during the period January 2003–December 2009. We discuss practical aspects of the method and the sometimes unexpected effects of using cell lysis buffer on the subsequent investigation of striation patterns on CBCs.

Abstract
Analysis of mitochondrial DNA in forensic samples is routinely carried out by direct sequencing of hypervariable regions within the non-coding displacement loop. Although the accuracy and sensitivity of this method cannot be questioned, it is both time-consuming and labor intensive. Finding a way to rapidly pre-screen forensic samples—prior to sequencing, to reduce the number of samples that need to be sequenced—would greatly benefit forensic laboratories. Herein, we describe an assay for discrimination of DNA from different individuals based on high-resolution melting analysis of the two hypervariable regions HVI and HVII of the mitochondrial genome. By clearly distinguishing the DNA melting curves of six different individuals, we show that this assay has the potential to function as a rapid and inexpensive pre-screening method for forensic samples prior to DNA sequencing.

Abstract
Due to the different types and quality of forensic evidence materials, their DNA content can vary substantially, and particularly low quantities can impact the results in an identification analysis. In this study, the quantity of mitochondrial and nuclear DNA was determined in a variety of materials using a previously described real-time PCR method. DNA quantification in the roots and distal sections of plucked and shed head hairs revealed large variations in DNA content particularly between the root and the shaft of plucked hairs. Also large intra- and inter-individual variations were found among hairs. In addition, DNA content was estimated in samples collected from fingerprints and accessories. The quantification of DNA on various items also displayed large variations, with some materials containing large amounts of nuclear DNA while no detectable nuclear DNA and only limited amounts of mitochondrial DNA were seen in others. Using this sensitive real-time PCR quantification assay, a better understanding was obtained regarding DNA content and variation in commonly analysed forensic evidence materials and this may guide the forensic scientist as to the best molecular biology approach for analysing various forensic evidence materials.

Abstract
Low volume (LV) amplification (1 microL) of nuclear DNA (nucDNA) on a chemically structured chip is an appropriate and highly sensitive method to simultaneously amplify amelogenin and 15 forensically relevant short tandem repeats (STR). In this study, a combined method using on-chip LV amplification of mitochondrial DNA (mtDNA) and subsequent on-chip LV cycle sequencing was established to obtain a method, which is sensitive and robust enough to allow reliable analysis of DNA amounts representing the single cell level. All the necessary steps of the procedure--except for the purification of the sequencing products--were accomplished within the same final 2-microL reaction volume.

Abstract
The forensic scientist often has to cope with problematic samples from the crime scene due to their minute size and thus the low amount of extractable DNA. The retrieval of DNA from swabs taken from the surface of the skin, for example, in cases of strangulation, can be especially difficult. We systematically investigated swabs taken from the skin (to obtain a genetic profile from the victim and also from a possible offender) and from sperm cell containing swabs using two extraction kits: the Invisorb forensic and the Invisorb spin swab kit (both Invitek, Germany). DNA quality and quantity were tested on ethidium bromide containing agarose gels and in a highly sensitive duplex-PCR, which amplifies fragments specific for mitochondrial and nuclear DNA. Absolute quantification was done using real time PCR. Samples, which were positive in the duplex-PCR, were also employed to genetic fingerprinting using the Powerplex ES and the AmpFlSTRIdentifiler(TM) kits. Our study shows that the easy-to-use Invisorb spin swab kit is very suitable for DNA isolation from swabs taken from the skin and also from sperm cells. Retrieval of cells from the skin with swabs moistened in extraction buffer, not in distilled water, led to a significant higher DNA yield.

Abstract
Sequence analysis of the human mitochondrial genome (mtDNA) has proven to be a valuable tool in forensic identity testing and the analysis of crime scene stains. In contrast to the very expensive sequencing technique, typing of different length variants can greatly facilitate screening of a large number of traces for their relevance during casework. Within the mitochondrial control region, a dinucleotide (CA)( n ) repeat locus is present. To assess the discrimination power of this marker, we have determined (CA)( n ) allele distribution and the frequency of heteroplasmy in a population sample of 2,458 Germans. The inclination to develop heteroplasmic mixtures (CA)( n )/(CA)( n-1) was positively correlated with the number of CA repeats in the mtDNA. In addition, we have studied the inheritance patterns of (CA)( n ) repeat sequence heteroplasmy in two pedigrees. In one pedigree, we also found a length heteroplasmy in the homopolymeric C-tract (nt 303-309). Our data show stable inheritance of heteroplasmy within the homopolymeric C-stretch, but rather unstable inheritance regarding the (CA)( n ) repeat locus.

Abstract
At the forensic autopsy of a sexual murder victim, some trace hairs, possibly belonging to the perpetrator, were saved. Initially, the analysis of a pubic hair shaft only revealed the presence of the mitochondrial (mt) DNA haplotype profile consisting of the (CA)(6) allele and the complete hypervariable region 1 (HV1) and 2 (HV2) sequence. Later, typing of some further telogene trace hairs, which had been stored for several years, yielded a nuclear short tandem repeat (STR) profile. We used both the mtDNA haplotype and the STR profile to start a DNA mass screening project involving 2,335 male citizens of the relevant communities. MtDNA screening was carried out by using the CA repeat amplification in combination with an SNP typing procedure based on the restriction site analysis of amplified d-loop sequences. The aim of our paper is to put mass screening with mtDNA up for discussion.

Abstract
In order to identify polymorphic sites and to find out their frequencies and the frequency of haplotypes, the complete D-loop of mitochondrial DNA (mtDNA) from 93 unrelated Czech Caucasians was sequenced. Sequence comparison showed that 85 haplotypes were found and of these 78 were unique, 6 were observed twice and 1 was observed three times. Genetic diversity (GD) was estimated at 0.999 and the probability of two randomly selected sequences matching (random match probability, RMP) at 1.2%. Additionally these calculations were carried out for hypervariable regions 1, 2 (HV1, HV2), for the area between HV1 and HV2 and for the area of the hypervariable region HV3. The average number of nucleotide differences (ANND) was established to be 10.2 for the complete D-loop. The majority of sequence variations were substitutions, particularly transitions. Deletions were found only in the region where HV3 is situated and insertions in the same place and in poly-C tracts between positions 303 and 315 in HV2. A high degree of length heteroplasmy was found especially in the regions of poly-C tracts between positions 16184 and 16193 in HV1 and between positions 303 and 315 in HV2. Position heteroplasmies were found in two cases.
