On Tuesday morning, gunfire ended a routine day at Purdue when a student fatally shot his fellow engineering classmate in a basement classroom.
Police are trying to determine why the shooter, Cody Cousins, shot Boldt a Wisconsin born engineering student and teaching assistant inside the Electrical Engineering Building.
John Cox the Police Chief said witnesses have said the shooting had been intentional, but said there had been no obvious indication that Boldt and Cousins had problems prior to Tuesday.
There were no other injuries and Cousins was arrested and was in jail awaiting his appearance in court on a charge of murder.
The shooting caused Mitch Daniels the President of Purdue University to cut short his trip to Colombia and to cancel all university classes both Tuesday and Wednesday.
Officials at the university praised the response of police but nonetheless students on campus remained jittery.
One student said he heard gunshots and a man scream. He had been in an adjacent classroom to the one where the shooting had taken place. He said he hid under a desk and was quite scared.
After the shooting, Cousins surrendered to police outside the Engineering building after firing as many as five shots. Former teachers said Boldt was someone who loved computers and robotics and was willing to help fellow students all the time with issues involving technology.
There is little known about the shooter. Cousins has an address in Centerville, Ohio and Warsaw, Indiana. Relatives of Cousins were not immediately found.
Tim Sands the Provost said police had acted quickly in alerting the campus of the danger via text messages. Police Chief Cox said that it was something the police practice a great deal.
Sands will become the Virginia Tech president in June, where a campus shooting in 2007 killed 33. He said Purdue would offer those who needed counseling all the help they needed.
