SOUTH MOUNTAIN – A 34-year-old South Mountain man is dead after a single-vehicle collision on County Road 1 Thurs., May 11.

The crash happened around 9:30 pm that evening when the 2012 GMC pickup truck left the roadway, rolled into the ditch, and struck a culvert.

A portion of the county road, between Irish Headline and Pleasant Valley Roads, was closed for several hours as police surveyed the aftermath.

The exact cause of the crash remains under investigation.

The name of the driver involved, Mathew Nelson, was announced the next day. Nelson died at the scene.

Though predeceased by his father, Nelson leaves behind his mother, Marion, and sister, Kate, and his two-year-old daughter McKenna.

A celebration of Nelson’s life is planned for tomorrow night (Thurs., May 18) at the Mountain Township Agricultural Society Hall in South Mountain. The family has planned an open mic format to allow those who knew Nelson to share memories and other stories. The evening gets underway at 6 pm.
