A woman who was detained at Pudong International Airport when she arrived on a plane from the United States wearing men's clothing and using a man's passport is being investigated in the murder of her Shanghainese husband in Lafayette, Indiana.
Police allege Chen Danlei, a Sichuan Province native, shot her husband He Lei in the head on August 20 at their home in Lafayette and then dismembered his body and stuffed it into the truck of their car.
He was reported missing by several friends on August 25, and his dismembered remains were found stuffed into five plastic bags in the trunk of the couple's Buick in a parking lot on August 30.
Both of Chen and He, 28, were students at Purdue University in Lafayette. Chen had given up her studies before the alleged murder, however.
Lafayette police said He was killed by a single gunshot wound to the head.
Before the body was found, Chen had already flown to Shanghai using He's passport. Her own passport had been confiscated by an American court after she failed to attend a hearing into a previous assault against her husband.
Police don't know how she was able to board an airplane in Chicago using her husband's passport.
When she appeared in Pudong International Airport wearing men's clothing, officials with the Pudong Entry Exit Frontier Inspection Station became suspicious and handed her over to the General Team of Criminal Investigation for questioning on passport violations.
"The investigation is almost finished," said a police officer who didn't want to reveal his name. "And the current evidence shows Chen was the murderer."
Lafayette police are working with China to extradite Chen, according to a statement Purdue University posted online.
But Shanghai officials wouldn't comment on that report, although they did say local authorities are collaborating with Lafayette police on the investigation.
China and the United States don't have an extradition treaty.
Chen was supposed to attend a hearing on August 26 into allegations she stabbed Chen while they were having sex last December.
The couple married in 2001. Chen  enrolled at the university in 2001 and He enrolled in 2002.
