As Congress steps up its efforts to get answers from a reluctant Obama administration about the terrorist attack on the U.S. mission in Benghazi, another father of one of the Americans killed in the attack is speaking out. Understandably, he wants answers.

Rene “Ray” Smith’s son, Sean Smith, a State Department official, was one of the four Americans killed in Libya when terrorists overran the U.S. compound in a sophisticated and pre-planned attack.

“He was murdered. He was murdered,” Smith told WTSP. “I want them to get the people who did this.”

But the grieving father wants more than just revenge. He wants the White House to explain exactly what happened in Libya on Sept. 11 and why repeated calls for help were denied.

“They haven’t done anything. My son and them dialed 911 for help and they wouldn’t help them…I want whoever did this, whoever didn’t answer their phone, I want them brought to justice too,” Smith added.

Smith, a former U.S. Marine, like many Americans, is also angry over the lack of honesty and transparency from the Obama administration following the Benghazi attack. He reportedly reached out to Rep. C.W. Bill Young (R-Fla.) and asked for help in getting to the truth. The father found a willing ally.

“He wants answers. Just like the rest of the country,” said the Congressman.”They want to know why these American heroes were asking for help and being denied the help?”

Smith had reportedly been estranged from his son for more than 10 years, but the dad was trying to reach out to his son before he was killed. “I was trying hard,” he said.

However, some good may come out of this unthinkable tragedy. Smith plans to connect with other family members in California, including Sean’s two children — his grandchildren.

“I loved my son very much,” said Smith. “He was extremely intelligent. And he did not deserve this.”

Ray Smith’s son may get permanent memorial at the Bay Pines V.A. Hospital, according to Young.

Attempts by TheBlaze to contact Smith were unsuccessful.

Charles Woods, the father of former Navy SEAL Tyrone Woods, became vocal after he says it became clear that the Obama administration was not telling the truth about Benghazi and what happened to his son.
