COLONIE, N.Y. -- Senators Charles Schumer and Kirsten Gillibrand are promising a military mother they will find out exactly what happened to her daughter.

Staff Sergeant Amy Seyboth Tirador died in Iraq earlier this month. She was laid to rest on Monday.

The Army says she did not die in combat.

Colleen Murphy holds the memory of her daughter close to her heart. More than two weeks after Staff Sgt. Tirador was killed, her family is still waiting for answers on who shot her to death inside her secure military base.

“I don't think they are withholding information,” Murphy told NEWS10, “I do believe that the Army wants to be absolutely sure of what's going on and what took place on the base is a very big deal.”

Murphy is now getting the support of at least two Washington lawmakers in her quest for answers.

Reading from a letter she recently received from Senator Gillibrand, Murpy says she is more confident that she will eventually know what happened to her 29-year-old daughter.

Reading Gillibrand’s letter aloud Murphy said, “Although there are no words to ease the sorrow, I send my deepest personal condolences to you.”

Senator Schumer has also vowed to help the Colonie family.

Speaking to NEWS10 on Thursday, Schumer said, “When a son or daughter serves our country, and makes the ultimate sacrifice, as this young woman did, her family deserves the whole truth and nothing but. And the Army is going to have to come clean and let the family know why Amy died and how she died.”

“That’s a big statement and I’ll hold him to it and I will hold anybody to it and I will ask for any help that I can get in any way shape or form,” Murphy said of Schumer’s words.
