ALBANY, N.Y. (AP) -- A New York industrial mechanic convicted of attempting to produce a mobile X-ray device intended to kill Muslims has been sentenced in federal court to 30 years in prison.

Fifty-two-year-old Glendon Scott Crawford, of Galway, also was ordered Monday by Judge Gary L. Sharpe to undergo a lifetime of supervised release after serving the sentence.

Crawford was convicted of conspiring to use a weapon of mass destruction and distributing information about weapons of mass destruction.

Crawford and co-defendant Eric Feight worked for General Electric in Schenectady. Prosecutors say the two conspired to design and build the device, which was to be set off remotely and would have exposed targets to deadly radiation.

Feight pleaded guilty to lesser charges a year ago and was sentenced to eight years in prison.
