Among the details that emerged Sunday about Adam Lanza -- who killed 26 people and then himself on Friday -- was that he enrolled at Western Connecticut State University at the age of 16, and earned a B average in several courses, The Los Angeles Times  reported.
Western Connecticut also has ties to two victims at the Sandy Hook Elementary School.  Jimmy Greene, who is on the jazz faculty at the university, lost a daughter, Ana, in the killings. And a nursing student at the university, Thomas Murphy, lost his mother, Anne Marie Murphy, who was a teacher's aide at the school.
Also, on Friday night, Massachusetts authorities arrested a junior at College of the Holy Cross and charged him with posting threats online Thursday (before the Sandy Hook killings) that he would go to a theater and "shoot it up," The Boston Globe  reported. The college suspended him Friday night, pending resolution of legal proceedings.
