Three people from an Oklahoma-based missionary group, including the daughter and son-in-law of a Missouri state representative, were shot and killed in a gang attack in Haiti as they were leaving an event at a church, the organization said Friday.

State Rep. Ben Baker and Missions in Haiti Inc. identified the victims as Davy Lloyd, son of the organization’s founders; his wife, Natalie Lloyd, Baker’s daughter; and Jude, its country director (the organization did not provide a last name). They were coming out of a church Thursday evening when they were ambushed by “a gang of 3 trucks full of guys,” Missions in Haiti said on its Facebook page.
