One confirmed dead, shooter in custody (and now IDed as Cody Cousins, 23)--and supposedly he was just aiming to kill target. Victim also IDed. They were both TAs in the engineering deptartment.
Vague details so far on incident in building at Purdue U in Indiana. WLFI-TV tweets it has confirmed at least "one shot." Varying reports of one in custody or two. (See photo here allegedly of one suspect on the ground with police gun on him. Close-up view here. And here, alleged shooter earlier with long gun outside building. And another.) Lockdown. No reports on injuries. More to come.
