CRAVEN COUNTY, NEW BERN -

A New Bern woman is killed in a wreck in South Carolina.

According to the Charleston County Sheriff's Office Sandi Weiss, 72, was killed when her car went off Highway 17 near the Awendaw Creek Bridge in Charleston. Investigators said Highway 17 was closed for several hours Saturday afternoon, as a rescue dive team and a coast guard helicopter tried to save Weiss.

"We're still kind of in shock. Everything happened so quickly," Weiss’ son Scott Weiss said.

A grandmother of six and a wife for more than 52 years, Scott said his mother's life was her family.

"She was our cheerleader, our Halloween costume designer, a teacher, a friend, a confidante and a mother," he explained.  

Scott said his mother was just 20 minutes away from visiting her oldest son, his wife and children. He said his mother spent most of her life helping others. Weiss was a nurse for many years and volunteered at the Merci Clinic in New Bern every week.

"She was dedicated. Even though she was just volunteering, that was something every Wednesday she'd do,” Scott said.

He said his father was in the air force for 20 years and his mother always supported the military. Scott said instead of sending flowers, the family asks that everyone donate to the Wounded Warrior Project and the Texas Scottish Rite Hospital research fund. He said it's a cause his mother donated to each year.

Investigators said they are still working to learn what caused the crash.
