The Defense Department has released the bios of the three who committed suicide in Gitmo:

Ali Abdullah Ahmed, the Yemeni, was a mid- to high-level al Qaeda operative with links to principal al Qaeda facilitators and senior membership, according to information released by DoD. Throughout his time at Guantanamo Bay, Ahmed was noncompliant and hostile to the guard force, and he was a long-term hunger striker from late 2005 to May 2006. Ahmed had been formally recommended for continued detention in Guantanamo Bay. Mani Shaman Turki al-Habardi al-Utaybi, a Saudi, was a member of Jama'at Tabligh, a militant recruitment group for al Qaeda and other jihadist terrorist groups, according to the DoD release. Jama'at Tabligh has been used by al Qaeda to cover travel throughout the world and has been banned in Saudi Arabia since the 1980s. Utaybi had been recommended for transfer to another country for continued detention in that country. Yassar Talal al-Zahrani, a Saudi, was an actual front line fighter for the Taliban who had traveled to Afghanistan to take up arms against anti-Taliban forces, according to the release. Zahrani facilitated weapons purchases for Taliban offensives against U.S. and coalition forces. He was captured by Afghan forces and participated in an Afghan prison uprising in Mazar-e-Sharif, Afghanistan, that resulted in the November 2001 death of CIA officer Johnny Michael Spann.
