Why was James Earl Ray in lisbon?

James Earl Ray was in Lisbon in 1968, primarily as a means of evading law enforcement after assassinating Dr. Martin Luther King Jr. in April of that year. He had traveled to Europe in an attempt to escape capture and was reportedly trying to secure a passage to other locations. Lisbon, being a port city with various international connections, offered him a temporary refuge. Ultimately, he was apprehended in London later that year.
