Grand Rapids (WZZM) - Sunday, the congregation of Holy Spirit Parish in Grand Rapids remembered four volunteers who died in Haiti.

The brakes on their vehicle failed causing them to go off the road and into a steep ravine.

Mary LaPonsie and Jim and Rita Cwengros have helped thousands of Hatians over the years. Matt Kutsche was one of the newest volunteers to join.

The day of the crash, another volunteer, Betty Krauss, was in the car behind her friends.

Father John Vallier says the group brought dental, medical, sanitation and education help to Haitians.

"Mary Laponsie and Jim and Rita Cwengros, they've been going since the beginning," he said."We've been doing this over 15 or 18 years."
