A sad story involving a former WNBC intern.

Boston University student and former intern at WNBC Erin Edwards and her 24-year-old brother were both killed by their mother inside their home near Atlanta, authorities said.

The mother, Marsha Edwards, then fatally shot herself, police said.

Erin interned for NBC New York’s digital team this summer while on a break from Boston University, the station reported Thursday.

“All of us in the newsroom just shocked to hear this news,” evening anchor Stefan Holt said in a newscast Thursday.

“Erin was a special person — exuberant, cheerful, a gifted story teller who just had a passion for journalism and it showed,” he added.

The New York Post reports that Edwards founded a medical equipment supply company. The children’s father, Edwards’ ex-husband Dr. Chris Edwards is an Atlanta-area surgeon.

A spokesperson for the family released a statement to WXIA.

“Dr. Christopher Edwards learned Wednesday of the death of his former wife, Dr. Marsha Edwards, and his two adult children, Christopher Edwards, Jr. and Erin Edwards,” the statement said.

“Dr. Edwards, his extended family and friends are in a state of grief and shock, and privacy of the family is paramount as arrangements are being made.”

Investigators were still trying to determine a motive for the killings.
