Frost had just graduated from USC and was back in school to get a second degree in cinematic arts.
His fraternity brothers and others that new him are shocked and saddened as they remember him.
Frost was "a free-spirited guy who loved life," said the victim's fraternity brother, Jens Midthun. "He made his choices based on how he would get the most fulfilling life. He had a perspective on life that I think a lot of us don't reach for a long time. He really saw the big picture."
Frost and two other students were walking near the campus on 27th Street and Orchard Avenue. That is when authorities say a lone male suspect yelled something at them prompting an argument and then a fight.
"The fight went to the ground and at a certain point it appeared that the fight was over," said LAPD Lt. John Romero. "The student reported to his friends that he felt something wet about his abdomen. They checked him out very quickly, he checked himself out, and they discovered that he was stabbed, and badly stabbed."
Frost was taken to the hospital, where he died.
Students, faculty, and staff at USC were notified of the killing by text message. According to USC Department of Public Safety, violent crime in the area surrounding the campus is down more than 20 percent.
"We think students who take reasonable precautions, that this is actually a relatively safe neighborhood," said Capt. David Carlisle from USC Department of Public Safety.
The 23-year-old's death comes on the heals of two other attacks in the neighborhood surrounding the campus. Two students were assaulted in two separate incidents recently, and now this. USC students Thursday were stunned by the news.
"I think USC should be a lot more responsible in terms of taking measures to make sure things like this don't happen. There has been two rapes and one killing.That's ridiculous," said USC student Cait Hubbard.
His death has prompted community activists in Los Angeles to call for peace.
The suspect has been identified as a black male. Frost was white and civil rights activists are saying that they do not want that to inflame racial tensions.
Police are saying that this was not race-related or gang-related.
