Students at Oikos University in Oakland, California, are still waiting for their classes to resume.
A lone gunman killed seven people there on Monday — and police are still collecting evidence.
Though it's called a university, Oikos does not have a large campus.
In fact, it's part of an industry of small, private colleges that can often go unnoticed.
Sometimes classrooms are found in old storefronts.
Many of the students are immigrants looking for a professional foothold in the US as Monica Campbell reports.
