Germanwings Crash Site Update: Tweets, Map, Pictures Showing French Alps, Wreckage, Victims, Vigils [PHOTOS]

As workers continue to comb through wreckage of the Germanwings plane that crashed Tuesday in a remote region of the French Alps, investigators are trying to piece together what exactly happened following the discovery that one of the pilots appeared to have deliberately crashed the plane. A voice recording from one of two so-called black boxes indicated that Andreas Lubitz, one of the pilots, appeared to have locked the captain out of the cockpit after he left, perhaps to use the bathroom.

The names of some of the 150 victims have been released, as have the nationalities of most, yet two days after the crash, a clear picture of who died and where they were from has yet to emerge. Body parts also have yet to be recovered, and the full process could take at least two weeks. Photos of the crash site and search efforts, the victims, vigils in memory of them, and more can be found below.

French military personnel make their way up a mountain towards the site of the crash, near Seyne-les-Alpes in southern France.

A search and rescue worker at the crash site on Wednesday:

Debris from the Germanwings Airbus A320 suggests the plane came apart on impact, not in the air.

On Wednesday, the day after the crash, French emergency services resumed work near the crash site:

The plane was en route from Barcelona, Spain, to Düsseldorf, Germany.

A topographical view of the crash site and search area:

German police gathered outside what was thought to be the home of Andreas Lubitz, who is believed to have deliberately crashed the plane:

The first black box provided key insight but not a full picture of what happened. The casing for the second box was reportedly found, but without the memory card containing important flight data.

All 150 people on board the flight were killed. Below, students at the Joseph-Koenig-Gymnasium high school in Haltern, Germany, which lost 16 students and two teachers in the crash, lit candles.
