ORLANDO, Fla. (AP) — A Jamaican arrested after trying to check luggage containing pipe bomb-making materials onto a flight home explained that he wanted to show his friends there how to make them, authorities said Wednesday.
Investigators were questioning whether Kevin Christopher Brown had ever been to Iraq — where he told them he'd seen similar bombs made, according to court documents — and looking into his mental health history after his arrest Tuesday at Orlando International Airport.
Authorities and airline officials repeated their assurances that passengers were never in danger.
Transportation Security Administration officials nonetheless touted the 32-year-old's arrest as a victory for new covert screening techniques involving plainclothes officers mingling with travelers.
Cleveland Laycock, a manager in TSA's behavioral detection program who was walking in civilian clothes, first spotted Brown approaching the Air Jamaica ticket counter. He told a uniformed subordinate to watch the man, and soon that officer called another for backup.
Behavior detection officers Frank Skowronski and Jose Zengotita wouldn't specify what Brown did that looked suspicious, saying it would undermine TSA's strategy. But they generally study facial expressions and body posture for fear, stress and deception.
"When he came up to ticket counter, he wouldn't look at anyone directly," Skowronski said.
The officers watched Brown drop off two bags to be checked, and had security officials set them immediately aside.
Inside were two glass vodka bottles containing nitromethane, a colorless liquid used as a fuel for drag racing, in manufacturing and as a cleaning solvent, the FBI said in a court filing. Brown told officials he hoped the liquor bottles would disguise the nitromethane, the document states.
The baggage also had a model rocket ignitor, galvanized pipes, end caps, two small containers containing BB's, batteries, a laptop, and instructions on how to make bombs, the FBI document said.
Dave Platt, a TSA bomb appraisal officer who searched the luggage, described the instructions as something that could be downloaded from the Internet.
He said the bags held virtually everything necessary to make a pipe bomb, and someone of his experience could have assembled it in about 15 seconds. But he said Brown's operation appeared to be "at the beginning stages of somebody starting to mess around, making pipe bombs."
"But regardless of whether they're new at the game or not ... when you make a pipe bomb, it still could kill you, whether you're a novice at it or you're really good at it."
Passengers were briefly cleared out of the ticketing area where Brown checked in for a flight to Montego Bay in Jamaica. Some flights departing Orlando were delayed up to two hours, airport spokeswoman Carolyn Fennell said.
Air Jamaica executive director Shirley Williams said the items could not have caused an explosion and the aircraft and its passengers were never at risk.
Brown first told authorities he wanted to detonate the materials on a tree stump in Jamaica, but later said he was going to show friends in his home country how to build explosives like he saw in Iraq, according to an FBI criminal complaint.
Federal prosecutors were reviewing Brown's mental health history and trying to determine whether he was ever in Iraq.
Brown did not speak at a brief court hearing Wednesday where he was ordered held without bail. Clarence Counts, Brown's court-appointed public defender, declined to comment as he prepared for a formal bond hearing Thursday.
TSA began pilot testing behavior detection officers in Orlando and other places in 2003, and steadily expanded the program. TSA Administrator Kip Hawley told The Associated Press such officers were already operating at every major domestic airport, and the agency would have 2,500 nationwide by year's end.
"I think this is the best layer of security that we have, and I think this is the best example of that layer," Hawley said at the time.
Richard Bloom, a dean who directs terrorism and security studies at Embry-Riddle Aeronautical University, said behavior detection can be effective. He said it takes appropriate research and training, as well as a detection system consistently tweaked, for the methods to be successful.
"This is really a very old issue, a very old topic, but has always been a very controversial one and remains so," Bloom said.
Brown is charged with one count of attempting to carry an explosive or incendiary device on an aircraft. The FBI believed his most recent address was in Gainesville, and that he was in the U.S. legally.
Jamaica's prime minister has ordered the Jamaica Constabulary Force to investigate Brown's activities in that country.
