Flags are flying at half staff across Montana in honor of the 13 victims killed in last week’s deadly shooting rampage at Fort Hood.

One of the men who died was a veteran of Montana's Army National Guard.

Michael Grant Cahill worked throughout Montana for many years as a Guardsman and as a physician's assistant at Fort Hood at the time of the shooting.

A St. Regis soldier stationed at Fort Hood tells us he was planning to go to the library the day of the shooting, but decided to stay home and eat first.

 Army Specialist Seth Hotchkiss says the library is in the area of where the shooting happened and he lives about a mile away from the site.

He says the shooting happened as he was at home eating. Phthises added that this isn't the first time he's been in a place where one of their own opened fire, killing several people.

His first time was earlier this year at Iraq's Camp Liberty where an U.S. Army sergeant shot five people.

“Both times just to have the attacks come from soldiers against soldiers. It really makes you wonder how safe you really are and where you're really safe at."

 Hotchkiss says there's heightened security at Fort Hood as investigators continue to look into the shooting.
