Br. Joyal, 62, was shot three times in the back in an apparent robbery April 25. He had just withdrawn $1,000 from a bank in the Haitian capital, Port-au-Prince, when two men approached him on a motorcycle, stole his backpack and shot him.
Haitian National Police said they arrested a suspect on April 29 but would not release further details.
Br. Joyal travelled to Haiti to help close the Society of Mary mission there. He was due to return to Canada May 3.
"It's a pity, a real pity," Fr. Gerard Blais, who oversees the Marianist missions in Canada and Haiti, said in a phone interview with Catholic News Service April 30. "We knew the dangers there. He knew the dangers there."
Br. Joyal was helping secure visas and passports for 10 young religious Haitian men who were being sent to Marianist properties in other countries as part of the closure of the Port-au-Prince mission. The Haitian mission was being closed because of a separate murder of a Marianist brother last year. On Aug. 29, a young Haitian brother was killed in a shooting, Blais said.
"It was a very bad situation," Blais said from his office outside of Quebec City. "We still don't know why he was murdered. We had to remove three others — two Canadians and one French — from Haiti after that murder. And the bishop asked us to close."
Blais said he asked Br. Joyal to travel to Haiti to close the mission "because he was used to working in hard situations."
Br. Joyal left Winnipeg as a young man in 1983 to open the Marianist ministry in India. He spent 20 years there, building a "care centre for street children, developing lay communities and promoting vocations to Marianist life, both lay and religious," according to a report on the mission published in 2006.
In 2004, he arrived alone in the Philippines, travelling to the Mindanao region, where clashes between Islamist separatist movements and the Philippine government had displaced hundreds of thousands of residents. By the time he left four years later, Br. Joyal had created a ministry focused on working with impoverished, homeless children and a centre dedicated to the formation of young men interested in Marianist religious life.
He first travelled to Haiti after the disastrous 2010 earthquake.
Br. Joyal's body was cremated, said Blais, who is working with Canadian authorities to have the remains sent back to Canada, where services will be held.
