U.S. Magistrate Ronald Boyce on Monday ordered that bombing suspect Steven Douglas Thurman be held without bail because of Thurman's threat to the community and himself.

Thurman, 32, 3843 W. 3390 South, is accused of detonating a bomb that critically injured an 11-year-old boy Wednesday. The pipe bomb loaded with nails was attached to a truck owned by the victim's father.The boy, Adam Cook, was listed in extremely critical condition Monday at University Hospital.

The U.S. attorney for Utah has charged Thurman with one count of possessing an unregistered explosive.

Federal attorney Mark Vincent said the bomb was detonated by remote control and the youth was just one of the intended victims. The evidence indicates "the defendant had no concern for human life," Vincent said.

Thurman would be a danger to the community and possibly a danger to himself because of a family history that includes suicide, Vincent said.
