Government officials say in Dzhokhar Tsarnaev's communication with interrogators, the surviving suspect has indicated that he and his brother acted alone and are not affiliated with a larger terrorist group.
They say he attributes their actions to radical Islamist beliefs.
Tonight we hear from the local Muslim community.
Worshippers at the Islamic center of Tucson say they are saddened by the attack last week.
In fact, the Tucson Imam released this statement:
"On behalf of the Muslim Community in Tucson; we condemn what has taken place in Boston no matter who is behind it. Terrorism and the killing of civilians has no place in Islam. Our religion came to preserve and protect the lives of human beings, God says in the Quran, and whomever kills an innocent soul, it is as if he has killed all of humanity.
"We extend our deepest condolences to the families of the injured and dead and pray for their recovery and healing from this terrible act. We extend our hope that the authorities will use the full extent of the law to prosecute those who committed these atrocities."
Tucson News Now spoke with a few Muslims at the center and they said they want people to know that the Muslim religion does not promote violence.
They say their religion is about love and caring for others.
"Radical Islam doesn't follow this," local Muslim Hamad Almojalli said. "They think that Islam should be encountered in every single place in the world by violence and that's wrong, they should do it in peace and that's what Islam is about."
Muslim leaders said their community community continues to grow in Tucson; right now, there are about 14,000 Muslims in Southern Arizona.
