Ep 4. Toxic Environment

Forensic Files II is an American documentary-style television series that revolves around investigations into real-life crime cases that were solved using forensic sciences. The show is known for its in-depth exploration of the techniques and technologies used in forensic investigations, as well as the dedication and hard work of the investigative teams involved. In season 4, episode 4, "Toxic Environment," the show takes us through one such case that involves the use of forensic science to solve a mysterious murder.

The episode begins by introducing us to a young couple, Dylan and Kristen, who lived in a small town in upstate New York. They were both avid outdoors enthusiasts and loved spending time camping, hiking, and mountaineering. Dylan, in particular, was a skilled climber who had even attempted some of the world's highest peaks. However, one day, he disappeared during a routine hike, leaving behind a devastated partner and family.

The local police department, along with search and rescue teams, launched an extensive search operation to find Dylan. However, weeks passed, and there was still no sign of him. It wasn't until a hiker stumbled upon his remains deep in the woods that the investigation took a grim turn from a missing person's case to a homicide investigation.

The case quickly became complicated, as there were no witnesses or suspects, and the whereabouts of Dylan's belongings, including his climbing gear, were unknown. The police had to rely solely on forensic science to piece together what happened to Dylan and to find his killer.

The forensic team began by testing the remains for any toxic substances, given that Dylan's remains were found in an area known to be contaminated with high levels of toxic chemicals. The lab results revealed several toxins in his body, including pesticides and herbicides commonly used in farms, which raised the possibility of foul play.

The investigators then turned their attention to Dylan's gear, which was also found near his remains. Forensic analysis of his mountain climbing equipment, including ropes and carabiners, revealed that some of the gear had been tampered with. Further investigation led the team to a storage unit belonging to Kristen, where they discovered several items of climbing gear that matched Dylan's, but with altered serial numbers and damage consistent with attempts to cover up.

The investigation also revealed that Kristen had a possible motive for killing Dylan. She was a chemist who worked for a company that produced chemicals for agricultural use, and Dylan had expressed his concern about the detrimental impact these chemicals had on the environment. Dylan had also been planning to leave Kristen and had started to distance himself from her.

The forensic team used DNA analysis to confirm that the damaged and altered climbing gear belonged to Dylan. They then conducted further tests on the gear to look for Kristen's DNA, and the results were positive. The team also found traces of herbicides and pesticides on Kristen's hiking boots and clothing, indicating that she had been in contact with the toxic chemicals.

After months of investigation, the forensic team had enough evidence to arrest Kristen for the murder of Dylan. At her trial, Kristen denied all charges and claimed that the toxic environment in the area was responsible for Dylan's death. However, the forensic evidence presented in court proved otherwise, and Kristen was found guilty of murder.

The episode ends with a summary of the case and the impact it had on the small town. The episode highlights the importance of forensic science and how it can help solve even the most complex cases. It also emphasizes the hard work and dedication of the investigative teams involved in solving such crimes.
