(CNN) -- Three people have been detained for questioning in Belize in the weekend killing of Gregory Faull, a neighbor of Internet pioneer John McAfee, who was being sought for questioning, police said. The detentions are routine in such investigations, said Raphael Martinez, a spokesman for the National Police in the Central American country. Faull, 52, was found dead with a gunshot wound to the back of the head on Sunday in his home near San Pedro Belize, on the Caribbean island of Ambergris Caye, Martinez said. Faull was killed after four of 11 dogs belonging to McAfee were fatally poisoned, said Wired Magazine Contributing Editor Joshua Davis, who said he had spent more than 100 hours with McAfee in recent months. Faull had frequently complained about the dogs barking, Davis said.
