LUBBOCK, Texas -- Luis Carlos Montalvan, a decorated Iraq war veteran who became a strong critic of the war and wrote about it, has died in El Paso. He was 43.
El Paso police Sgt. Enrique Carrillo on Monday said Montalvan was found in a hotel room in downtown El Paso late Friday.
"A renowned author and speaker was found dead inside a downtown hotel room on Friday night," Carrillo said in a statement.
"Central Regional Command officers responded to the Indigo Hotel on a welfare check," he added. "The officers entered the hotel room and found the body of Luis Carlos Montalvan. There were no signs of foul play and cause of death is pending investigation by the Medical Examiner's office."
There was nothing readily apparent at the scene to indicate the death was a suicide, Carrillo later told a reporter.
The medical examiner's office has not completed a preliminary autopsy report.
Montalvan served 17 years in the Army, doing two tours in Iraq. He received two Bronze Stars and the Purple Heart.
Tuesday, his service dog, was the subject of Montalvan's book, "Until Tuesday: A Wounded Warrior and the Golden Retriever Who Saved Him," which became a New York Times bestseller.
Some Army colleagues said Montalvan embellished his account of the incident that led to his Purple Heart.
A donation page set up to memorialize Montalvan by contributing to the nonprofit Educated Canines Assisting with Disabilities, or ECAD, stated the dog Tuesday is alive and well.
"Tuesday is safe, happy, and will continue to be cared for by the ECAD family," it stated. "Luis's mission of advocacy and being an ECAD ambassador will continue through Tuesday."
