HOUSTON – The survivor of a deadly explosion at a Texas City apartment building has been indicted on three federal charges related to making bombs.

The indictment accuses Curtis Lee Jetton, 22, of conspiring with his roommate, Matthew Robert Rugo, 21, who died when bomb-making materials exploded in their apartment in July 2006, to build bombs using TATP. The duo learned about the material on the Internet. Mr. Jetton allegedly provided metal shavings from his work to use in an explosive mix that they placed in pipes, beer bottles and sandwich bags. The makeshift bombs were detonated in fields and under vehicles, the indictment says.

The indictment links Mr. Jetton and Mr. Rugo to an anarchist group called the Glass Desert Underground. It doesn't say whether they were targeting anything.
