Dog attack: the application of canine DNA profiling in forensic casework

Area of Science:

• Forensic Science
• Genetics
• Animal Forensics

Background:

• Dog attacks pose a significant public safety concern in Australia, with over 100,000 incidents annually, many remaining unsolved.
• These attacks result in injuries to humans, fatalities to domestic animals, livestock, and native wildlife.
• Biological evidence, such as saliva or hair, is frequently left at attack scenes, offering a potential avenue for identification.

Observation:

• Canine biological evidence collected from victims or attack sites is crucial for forensic investigations.
• A laboratory utilizes a validated panel of 11 canine-specific autosomal short tandem repeat (STR) markers for DNA profiling.
• Standardized methods for evidence sampling, DNA profiling, and statistical analysis are employed.

Findings:

• The study presents case studies demonstrating the application of canine DNA profiling in real-world investigations.
• Successful identification of canines involved in attacks through DNA analysis has been achieved.
• Challenges encountered in evidence collection, DNA extraction, and interpretation are highlighted.

Implications:

• Canine DNA profiling offers a powerful tool for resolving unsolved dog attacks, enhancing justice for victims.
• This forensic capability can aid in preventing future attacks by identifying and managing dangerous dogs.
• The methodology contributes to the broader field of animal forensics and wildlife crime investigations.
