Finding Killers with Thermal may be a topic not often thought about. When it comes to search and rescue or searching for a fugitive on the run… thermal is incredibly important to get the job done.

On August 31st, 2023 a murderer escaped from a Chester County prison which triggered a massive manhunt.

In 2017, Danelo Cavalcante was originally convicted in Brazil for homicide but then fled to the United states and successfully lived at large for 4 years. He somehow obtained a job and a girlfriend in the states. When his United States girlfriend found out about his convicted murder in Brazil she threatened to turn him in. So, instead of risking getting locked up and deported from the United States he chose to commit yet another murder.

This triggered a massive manhunt which brought in US Border Patrol and prompted hundreds of Pennsylvania State Police officers to join the search in Chester County. After almost two weeks of searching, on September 13th they finally located Cavalcante hiding in a wood pile using a thermal.

If you truly want to own the night the first thing you need to do is figure out how to get both night vision and thermal in your kit.
