who killed pvt. danny chen?

Some follow-up on the death of 19-year-old Pvt. Danny Chen, the soldier who mysteriously died while serving in Afghanistan last month after allegedly being subjected to repeated "racially charged bullying." He reportedly died from a gunshot to the head.

Unfortunately, that's pretty much all we know. While Chen's family has been assured that a thorough investigation is being conducted, the military hasn't been very forthcoming with information about what really happened to Danny: Soldier's Death Raises Suspicions in Chinatown.

Private Chen kept a journal while deployed, relatives said, but military investigators have so far shared only three pages of it with the family. On one, a cartoonish face with an angst-ridden expression is scrawled alongside the misspelled message: "Watever happens happens."

On another, a list of notes, in what looks like Private Chen's handwriting, describes procedural failures, including "Didn't clear weapon," "Didn't hydrate," and "No attention to detail (little things)."

Relatives said they had no idea what to make of the pages. The military's decision to release them while retaining the rest of the journal has only added to their bewilderment.

A spokesman for the Army Criminal Investigation Command said officials in Afghanistan were conducting a "thorough, in-depth investigation" into Private Chen's death.

"We're not only investigating to determine the cause and manner of his death, but also the circumstances leading up to his death," said the spokesman, Christopher Grey. "We take this investigation and the tragic loss of Private Chen very serious and will not close our investigation until we are fully confident we have determined exactly what transpired."

He added that no other details would be released until the investigation was completed.

Can you really blame Chen's family for being frustrated and bewildered about the lack of transparency in this investigation? And I'm certainly not the first person to point out the alarming, eerie similarities between Chen's death and the recent suicide of Marine Harry Lew.
