BOSTON (CBS) – A Boston University student was killed at her home in Georgia in an apparent murder-suicide. Police believe it was her mother that murdered her and her brother.

Just more than a week before Erin Edwards was set to begin her junior year at Boston University, the 20-year-old was found dead.

Cobb County Police said the young woman and her 24-year-old brother Christopher had suffered gunshot wounds. Their mother, 56-year-old Marsha Edwards was also dead; it appears her wound was self-inflicted.

Investigators could be seen collecting evidence from the townhome all throughout the night Wednesday.

A source told CBS46 News in Atlanta police found the three bodies after Marsha Edward’s ex-husband requested a wellness check at the home when he became worried about one of the adult children.

Marsha Edwards had a doctorate in medicine and owned a medical consulting business.

Boston University told WBZ Erin Edwards was an active student within the College of Communications and known to many on campus. The university is in the process of notifying students and faculty close to Edwards of this “awful tragedy.”

According to Edwards’ social media accounts, she was a digital news intern in New York this summer. Classes resume at Boston University a week from Tuesday.
