Investigators are still trying to determine what caused Ivan Lopez’s Wednesday shooting spree at Ft. Hood in Texas. The rampage left four dead and another 16 wounded.
“We only have one suspect,” said Chris Grey, spokesman for the Army’s Criminal Investigation Command. Grey was speaking at a Monday news conference and did not take any questions.
“We are fully committed to this investigation and we will continue to pursue investigatively all leads,” he said in a Fox News story.
The findings from the ongoing investigation indicate that the violence was touched off during a verbal altercation after Lopez was denied a request for leave. According to Fox News officials believe that proves the shootings were the result of flared emotions and should put to rest speculation that the 34-year-old Army specialist was suffering from Post-Traumatic Stress Disorder. Army officials have expressed doubt that Lopez’s single four-month tour in Iraq could have caused PTSD.

But Lopez had been undergoing treatment for anxiety and depression according to one senior official familiar with the investigation. CNN indicates that Lopez had also recently asked to be transferred from the base, claiming that he was being picked on and taunted by fellow soldiers.
Another unnamed official, interviewed by CNN, said that investigators will continue to review the suspected shooter’s mental health history. They will also conduct interviews to investigate his interactions with fellow soldiers.
Records show that Lopez had been attending regular mental health appointments in recent months. He had also been prescribed medications at his previous post of Ft. Bliss. Medical examiners will try to determine what drugs he was prescribed and if he had taken them correctly. Possible interactions between drugs will also be investigated.
What investigators do know is that Lopez fired 34 shots from a .45 caliber handgun before the turning the gun on himself. He died at the scene.
