The "7th Annual March to Stop Executions", which was sponsored by a record number of 50 organizations, was held October 28, 2006 and included family members of Carlos DeLuna and Cameron Todd Willingham, who both had been the subject of separate investigations by the Chicago Tribune that concluded they could have been wrongfully executed. Standing outside the gates of the Texas Governor's Mansion with hundreds of supporters, the families of Willingham and De Luna delivered separate letters to Governor Perry asking him to stop executions and investigate the cases of Willingham and De Luna to determine if they were wrongfully executed. After DPS troopers refused to take the letters, Mary Arredondo, sister of Carlos De Luna, and Eugenia Willingham, stepmother of Todd, dropped them through the gate of the governor's mansion and left them lying on the walkway leading to the main door. The "8th Annual March to Stop Executions" was held in Houston on October 27. 2007. The "9th Annual March to Stop Executions" was October 25, 2008 in Houston. The "10th Annual March to Abolish the Death Penalty" was attended by hundreds of people on October 24, 2009 in Austin.
