Tirador's mom told us this week she spoke with a special agent from the military and received some more information. While the family is happy to get some answers, some answers lead to more questions.

Two flags fly in front Staff Sergeant Amy Seyboth Tirador's mother's house. Colleen Murphy says the flags serve as a way to remember Tirador, a constant reminder to find out what happened to her.

"She was an excellent soldier, an excellent person, she was a staff sergeant with a heart and everyone knew it," Murphy said.

Tirador was on her third tour of duty, this time working as an interrogator on a military base in Iraq. This week, the military provided more insight into what happened to Tirador on November 4th, the day she died.

"I did find out Amy was going to work at 8 p.m. in the evening and everything was fine and she just didn't show up to work," Murphy said.

Maintenance workers discovered Tirador's body in a building at 1 p.m. the next day. She suffered a single gunshot wound to the back of the head. The military says it's a homicide or suicide. Murphy says it's murder.

"In my personal opinion, the person or persons who did this to my daughter were extremely smart and set this up exactly to look like a suicide. Absolutely no question in my mind," said Murphy.

So far, the military won't go into detail on if there are any suspects. They do say Tirador was not shot by a sniper since the shot was taken at a closer range. Tirador's mom wants all the answers and right now she's not getting them.

"The investigation is at such a high profile that the questions that I think I should be able to know I can't know because it could jeopardize the investigation," Murphy said.

Now, Tirador's body lies at Saratoga National Cemetery, where she was buried with full military honors. She is the first woman from the Capital Region to die in the wars in Iraq and Afghanistan. Her family now waits yearning for full closure.

"This momma's not going to stop," Murphy said. "I will not stop until I know it's the truth without a shadow of a doubt. No matter what the circumstances are. No matter who it may involve."

Tirador's mom has also enlisted the help of Senator Charles Schumer and Senator Kristen Gillibrand. She hopes the pair will help speed up the process of finding out exactly what happened to Tirador.

Right now, the military says they hope to give Tirador's family the complete answer in three months to a year.
