DENVER — Prosecutors in the trial of Timothy J. McVeigh presented evidence and testimony Friday that suggested McVeigh and Terry L. Nichols made two large purchases of highly explosive ammonium nitrate fertilizer in the months before the 1995 bombing of the federal building in Oklahoma City.
Using sales receipts and testimony from an official at a Kansas grain cooperative, the government showed that there were two large cash transactions in the fall of 1994 in which they contend McVeigh and Nichols used an alias to obtain as much as 4,000 pounds of the highly explosive fertilizer.
Robert Nattier, president and general manager of the Mid-Kansas Co-Op, said that a man who called himself Mike Havens purchased 40 bags of ammonium nitrate weighing 50 pounds each at the co-op's McPherson, Kan., branch for $228.74 on Sept. 30, 1994. On Oct. 18 he bought 40 more bags for the same price.
Prosecutors contend that the name Havens was used as an alias as the two former army buddies began collecting bomb components. On April 19, 1995, the Alfred P. Murrah Federal Building was destroyed by a large truck bomb allegedly carrying a mixture of ammonium nitrate and fuel oil. The bombing killed 168 people and injured more than 500.
