Speaking before his execution, Mark Stroman described hate as "pure ignorance".

A multiple murderer who went on the rampage after the 9/11 attacks, killing two people he thought were Arabs, has been executed in the US state of Texas. Mark Stroman, 41, died by lethal injection despite last-minute representations by his lawyer at the US Supreme Court.

This long and winding road for Stroman began when Bin Laden unleashed his attack on September 11 against the Twin Towers in New York City .

Stroman's sister went to work in New York that fateful day never dreaming it would be her last morning on earth.

Infuriated by the death of his sister, Stroman embarked on a shooting spree which resulted in the deaths of a Pakistani man, an Indian immigrant and a Bangladeshi man.

Stroman termed his shooting of three people of Middle Eastern descent as a "patriotic" acts in response to the September 11, 2001, terrorist attacks.

On October 4, 2001 Stroman allegedly shot and killed Vasudev Patel in the course of an attempted robbery at a Texas gasoline station in Mesquite.

Stroman entered the store during the early morning hours and demanded money from the unsuspecting Patel who reached for a .22 caliber pistol that he kept under the cash register. He didn't actually touch it though.

The condemned man then shot the unarmed Patel in the chest.

A surveillance video showed to jurors that while Patel lay dying on the floor, his shooter demanded that Patel "open the register or I'll kill you."

On September 15, 2001, Stroman shot Waqar Hasan in the head. Hasan was grilling hamburgers in his Dallas business at the time.

Stroman later allegedly told a fellow inmate that the murder of Hasan was his ninth crime of that type. He also confided that he had a .44 pistol and intended to start shooting everybody at a shopping mall because of "all the Middle Eastern people there."

Then on September 21, 2001, Stroman ironically shot Raisuddin Bhuiuian, who is now a supporter of Stroman's clemency request. Bhuiuian was working in a convenience store when he caught a bullet.

Stroman allegedly told his fellow prisoner that he had performed a patriotic duty, saying that his country "hadn't done their job so he was going to do it for us."

In his final weeks Stroman's plea for clemency was backed by Rais Bhuiyan, who was shot but survived.
Mr Bhuiyan had said that killing Stroman was "not the solution".

The execution at Huntsville prison was delayed slightly by the final legal appeals, before Stroman was taken to the death chamber.
"Even though I lay on this gurney, seconds away from my death, I am at total peace," he said.
"God bless America. God bless everyone," he said. "Let's do this damn thing."

Stroman was pronounced dead wednesday at 2053 CDT (0153 GMT) .07.20.2011.

'Hate is ignorance' Speaking to the BBC before Stroman's execution, Mr Bhuiyan, 37, said Stroman was guilty of "hate crime", but warned that his death would not achieve anything.
"His execution will not eradicate hate crimes from this world. We will just simply lose another human life," Mr Bhuiyan said.

Stroman's execution was the eighth in Texas during 2011 so far, and came as his lawyers sought a last-minute stay at the nation's highest court.

They cited the "significant surprise" of Mr Bhuiyan's support, and argued that Stroman's path to "this violent frenzy" was not made clear by defence lawyers during earlier trials and appeals.

Stroman admitted the killings, saying he was motivated by anger at the 9/11 attacks and wanted to take revenge on Muslims - or people who resembled Muslims.

"I had some poor upbringing and I grabbed a hold of some ideas which was ignorance, you know, and hate is pure ignorance. I no longer want to be like hate, I want to be like me," he told the BBC.
