A 20-year-old Boston College student has been missing since he left his Brookline apartment on Monday, police said. Stephen Ziska, of Brooklyn, N.Y., is a junior biology and computer science major. Police said he has not been in contact with any family members or friends since his disappearance. Brookline police are leading the investigation, said Jack Dun, spokesman for Boston College. He said the college sent out an e-mail informing students of the situation. Dunn described Ziska as a “talented student” who previously attended Regis High School on the Upper East Side of Manhattan.
