David Coleman Headley, charged in Chicago with playing a role in the 2008 Mumbai, India bombings that killed about 170 people, is expected to plead guilty Thursday, the Chicago Tribune reported.
The Tribune reported that he has been cooperating since his arrest in October. His attorney would not comment to the paper on whether the government has agreed not to pursue the death penalty.
Authorities have alleged that Headley traveled to India to scout targets for the attack. Another person charged in the Chicago case, Tahawwur Rana, has pleaded not guilty.
The two are also charged with plotting to attack a Danish newspaper for publishing cartoons that were viewed as being very offensive in the Muslim community.
