Friends and police said Knoop, who is from Chicago, was alone at the time and apparently knew his assailant.
Detectives have taken two statements, but no arrests have been made in the case.
The motive for Knoop’s murder is still not known, said John Munsell, chairman of the board for the Quisqueya Chapel in Haiti where Knoop worked.
“In terms of us here at the chapel, we are not aware of any conflicts he had with people,” Munsell said. “He was well liked.” via | Fox News.
