The University of Texas campus has lifted a campus lockdown after the apparent suicide of a young man who, according to witness accounts, burst into the Perry-Castañeda Library in a business suit and a face mask, wielding an AK-47. No one else was injured in the morning shooting, but the incident conjured up frightening images of the 2007 Virginia Tech massacre.

Despite rumors this morning that authorities were searching for a possible second suspect, no evidence has surfaced that anyone else was involved in the incident.
