GUAYANILLA, Puerto Rico —
The family was not aware that Lopez was receiving any treatment for mental problems, the spokesman said.
He grew up in Guayanilla, a town of fewer than 10,000 people, where small, well-kept houses are painted bright colors. The house he grew up in was empty Thursday. It is a one-story, concrete home painted white with green trim.
There are few jobs in the town, and many young people have joined the military in recent years. A young woman whose parents live in the town, 33-year-old Army Spec. Aleina Rodriguez-Gonzalez, was killed in Iraq in 2005.
The mayor described Lopez as somewhat introverted and passionate about music. His parents attended school functions, and they seemed close.
Puerto Rico police officials and Torres, the family spokesman, said Lopez had worked as a state police officer from 2000 until he received leave to serve in the military.
Torres said Lopez's relatives are devastated, trying to comprehend the shooting.
"He was a very laid-back person. I would even say a bit shy," Torres said. "That's why we are so surprised."
In El Paso, Texas, where the Lopez family lived for about two years before heading to Fort Hood, Noah Georges lived across the hall. They were a quiet family, with a small daughter, he recalled.
Although Georges never heard the couple argue, "you could see there was tension between them."
"I never saw them leave the house together. It seemed obvious they didn't talk to one another much," Georges said.
In Killeen, Texas, where the family moved after Lopez was transferred to Fort Hood, neighbors in a three-story, blue and gray apartment building described him as friendly.
Shaneice Banks, a 21-year-old business management student who lives downstairs from the Lopezes, said her husband, who also works at Fort Hood, helped the family move in just three weeks ago. Hours before the shooting, Banks said, she ran into Lopez when he came home for lunch.
