Authorities are ruling out radicalism or Jihad in a fatal shooting at the largest active duty army base in the United States.  A soldier in the motor pool opened fire on his colleagues, killing four people including himself and wounding at least eleven more.

It started around 4:30 PM local time Wednesday afternoon at Fort Hood in Texas.  Witnesses described hearing about 20 shots being fired, alarms went off, and tens of thousands of US Army Soldiers and their families on base were told to shelter in place immediately.

The motive is unclear in the early stages of the investigation.  Several sources have identified the suspect as 34-year old Ivan Lopez, who lives in the Fort Hood area.  President Barack Obama, at an event in Chicago, promised that an investigation would get to the bottom of what happened.

The military sent the eleven wounded people to local hospitals for treatment, and their conditions range from stable to extremely critical.  One doctor said it was “another sad day for central Texas”, referring to an earlier mass shooting.

Fort Hood was where, in 2009, Army Major and psychologist Nidal Malik Hasan shot and killed 13 people and injured more than 30 others in revenge for what he believed was the US military’s shabby treatment of Muslims in the Iraq and Afghanistan Wars.  He was sentenced to death in August 2013 and remains on death row today.
