Missing Flight MH370 Victim's Girlfriend Got Chilling Death Threat By Text

The girlfriend of an American passenger who was onboard the missing flight MH370 has received death threats and pornographic images sent to her phone and suffered two break-ins at her apartment since the plane disappeared.

Sarah Bajc was the partner of Philip Wood who vanished two months ago along with 238 others on the Malaysia Airlines flight.

She told NBC News she received an instant message from a Chinese number saying: "I'm going to come and kill you next".

Bajc said she also received several explicit pictures and creepy phone calls from the same China-based number. Before the tragedy, Bajc had been preparing to move from her home in Beijing to live in Kuala Lumpur with Wood, who worked for IBM.

The calls and messages began after a break-in at her apartment, two weeks after the plane disappeared, something which she described as "the straw that broke the camel's back".

“Whoever came wasn’t very careful because I’m a real neat freak, so it was immediately apparent to me that some things had been moved,” she said.

“My housekeeper was out of town so it couldn’t have been her and I got home before my son got back. The password on my safe had been reset which happens when you try the wrong code three times."

“The second time was a couple weeks later and my neighbour saw two people leaving my apartment. I have no illusions of privacy here [in China].”

The calls stopped after Bajc asked the FBI to investigate, she said.

No trace of the plane has been found since it disappeared on March 8. On Saturday, an Australian naval vessel departed for a second mission to scan the part of the Indian Ocean where the longest sonar "ping", purportedly from a black box, was heard over a month ago, Reuters reported.

Australia, China and Malaysia earlier this week pledged they would not to give up searching for the plane, even though all surface debris is now likely to have become waterlogged and sunk.
