A tip for war criminals hiding out in foreign countries: if you want to avoid detection, don't wander across the U.S.-Canada border by foot.

That's exactly what accused war criminal Jean Leonard Teganya, 42, did shortly before he was arrested in Houlton, Maine, a quaint little town that is known for the annual Maine Soap Box Derby, Wiggy's Trading Post, and now, a Rwandan fugitive. 

Teganya, a former medical intern, was allegedly involved in the deaths of almost 200 Tutsis at a Rwandan hospital. His family fled in 1994 to Congo, Kenya, and then India before ending up in Quebec in 1999. 

The 1994 Rwandan genocide saw the death of almost a million Tutsis in half a year.

In 2011, the Canadian government put a warrant out for his arrest and deportation. 

Teganya, the son of a Rwandan war criminal serving a 22-year sentence previously argued that if he returned to the country he would be detained without being charged

Division Chief Patrick Murphy spoke about the August 3 arrest with The Wire.

"Our border patrol agents received a call from a concerned citizen that they had seen a suspicious individual walking away from the border in Houlton," Murphy said.

The officers responded to the tip, carried out a background check, and, after determining Teganya was in the United States illegally, took him into custody. 

Murphy praised the people of Houlton, a rural town with just over 6,000 citizens for serving as an "extra set of eyes and ears" in the arrest of an international fugitive.   

"These are very small tightly knit communities where you know all your neighbors. "When people see someone they don't know, they know to say something," he said.
