Passenger had murder directions on computer: US

LOS ANGELES (AP) - A teacher arrested at Los Angeles International Airport wearing a bulletproof vest and with checked bags containing knives, body bags, a smoke grenade and other weapons also had files on his computer detailing how to kidnap and kill people, federal authorities disclosed on Friday.

In addition, Yongda Huang Harris had files revealing he has a "strong interest" in sexual violence against girls, including a video titled Schoolgirls in Cement, Assistant United States (US) Attorney Melissa Mills said.

One publication was entitled Man Trapping and showed how to hunt and trap humans, she said.

The prosecutor detailed the discoveries during a court appearance by Harris, 28, a Boston University graduate who had been working in Japan as a junior high school teacher.
