Sleep deprivation and self doubt are what led an Army official to commit suicide just two days before assuming control of U.S. Army Space and Missile Defense Command at Redstone Arsenal, an official said this week.

Maj. Gen. John Rossi, 55, hanged himself July 31 a little more than a week after he and his wife moved from Fort Sill, Oklahoma, to Redstone Arsenal. Details of the investigation were provided by Army Secretary Eric Fanning to the Army Times.

Officials attribute Rossi’s suicide to a wave of career and medical stress that impaired his judgment and distorted his sense of self-worth. A report into his death revealed Rossi slept only five hours per night and had kept that schedule for most of the previous two years.

The Army Times reported his death has prompted an Army-wide review of mental health issues in the general officer corps to be headed up by a three-star general.

“It’s not because we felt we had some burgeoning, endemic problem,” Fanning is quoted as saying. “It’s because one is too many, and it’s always good to take a knee, take a breath, and see if there’s something new or that has developed because something’s changed.”

The Army Times report says Rossi’s wife told investigators he revealed his doubts about his fitness for the new job, according to the investigation.

“He told her that there was ‘so much information’ associated with the job that he didn’t know or understand, and that he ‘didn’t think he was smart enough for the job,’” the report said.
