Four brave souls were maliciously murdered last week in Haiti after their caravan experienced brake failure, careened off the side of a mountain and landed into a ravine. The four people involved were on a mission with their church when everything went wrong.

The group was traveling in a Toyota Landcruiser that had just taken a sharp turn when its brakes failed. The vehicle, one of five traveling in a caravan carrying the team members, crashed through an iron barrier and plunged into the nearby ravine, says M Live News.

The four Americans inside were taken to a hospital in nearby Jacmel. Some died in the hospital, while others were pronounced dead at the scene. The driver and interpreter, Martin Glisil, was seriously injured and hospitalized, said the director of the missionaries.

A prayer service is scheduled for 6:30 p.m. Saturday at Holy Spirit Parish, 2230 Lake Michigan Drive NW, in Grand Rapids. Bishop Walter Hurley is expected to attend as members gather to mourn those lost in the tragedy.

Remaining members of the Haiti missions team are reportedly traveling back to the United States in a corporate plane affiliated with Amway. They are expected back in the states at some point on Saturday.
