Seymour warned the students at Sunday's vigil to never travel alone.
"She absolutely had no chance in this, but if there's someone else in the car, there's actually a chance," he said.
Samantha's boyfriend and friends shared stories of the political science major who was bound for Drexel University's Thomas R. Kline School of Law.
"The last words she said to me over FaceTime on Thursday was that I was her person, and that she loved me, and that she could truly be herself around me," her boyfriend said.
Samantha's funeral is scheduled for Wednesday, April 3 in Princeton Junction, New Jersey.
