Cameron Seth Martin, 11, Kayla Beth Martin, 9, and Kendra Jane Martin, 7, killed, and six people injured in collision involving buggy on Condensery Road in Bushnell Township, Michigan

WOOD-TV reports that State Police say the pickup truck crashed into the rear of the buggy about 8:30 a.m. Sunday in Bushnell Township, just southeast of the village of Sheridan in central Michigan.

Police say seven of the couple's children were in the buggy when the crash happened Sunday near Sheridan in central Michigan. Two sons, ages 12 and 7, and a 9-year-old daughter were killed.   

Grenhoe was among dozens of neighbors who have stopped by with a kind word and a helping hand after the Martin family was torn apart Sunday morning when a pickup truck struck the family's horse-drawn buggy, killing three of their seven children and severely injuring the parents, Paul and Judith Martin.
