The Professor Kasin Suvatabhandhu Herbarium, established in 1960 at Chulalongkorn University in Bangkok, Thailand, plays a crucial role in the nation's forensic science sector. This institution houses over 20,000 preserved plant specimens, which are utilized to provide critical botanical evidence for law enforcement in resolving criminal cases. By analyzing plant materials, the herbarium assists in establishing links between suspects and crime scenes, and in reconstructing the sequence of events.
Science Service Officer Mrs. Parinyanoot Klinratana has emphasized the practical impact of the herbarium's work. Plant fragments found on suspects' clothing, for example, have been analyzed to pinpoint their geographical origins, potentially linking individuals to specific locations. The herbarium has also supported the Customs Department by identifying particular plant species, which is essential for regulatory compliance and trade. These applications demonstrate how the precise identification of plant life extends beyond academic research to provide tangible support for legal and commercial sectors.
Forensic botany, the application of plant science to criminal investigations, has a history dating back to the early 20th century, with early cases demonstrating its utility in solving crimes. Plant evidence, such as leaves, pollen, seeds, and roots, can serve as crucial information that might otherwise be overlooked. This botanical evidence can link suspects to crime scenes, identify geographical locations, and help reconstruct the timeline of events. The significance of this evidence is underscored by the need for meticulous collection and preservation at the crime scene itself, as even small overlooked fragments can be pivotal.
Beyond its role in forensics, the Professor Kasin Suvatabhandhu Herbarium functions as a vital national plant database. This extensive collection supports Thailand's broader commitment to biodiversity conservation and adherence to international regulatory standards. The preservation of these specimens ensures their long-term usability for research, contributing to a deeper understanding of Thailand's rich flora and its ecological significance. The herbarium's work exemplifies how specialized scientific knowledge can be a powerful tool for justice and for safeguarding natural heritage.
