Refinery worker arrested for threatening violence
The FBI arrested a Chevron employee Thursday on charges of threatening to blow up a refinery that makes 4 million gallons of jet fuel daily for Los Angeles International Airport. Ronald Denton, 37, had told a psychologist he planned to bomb the refinery and kill a large number of employees, and had purchased assault rifles and ammunition, federal prosecutors said.
Assistant U.S. Atty. Dave Fields said a search of Denton's condominium found a .30-caliber SKS assault rifle and 1,000 rounds of ammunition, two handguns, and a book on explosives. No explosives were found.
The alleged target was a refinery in El Segundo, near the airport, operated by Chevron Products Co., a division of Chevron USA.
Photos spy volcanic plumes on fiery moon of Jupiter
Twin volcanic plumes that rise 250 miles above the surface of Jupiter's fiery moon Io appear in images taken by two NASA spacecraft and released Thursday. Scientists have known about one of the towering plumes for the past four years. It has continued to spew gas and dust from a volcano called Pele each time the Galileo probe has flown past Io. But when Galileo was joined at Jupiter this winter by the spacecraft Cassini, the two probes caught a second plume.
Peering at Io in ultraviolet wavelengths on Jan. 1 and 2, Cassini spied the new plume near the moon's north pole. Scientists working on the Pasadena-based NASA mission hope Galileo will give them a closer look at Tvashtar when the spacecraft passes just 224 miles above the area in August. The craft will fly directly through the plume if it's still present.
