Los Angeles pioneer historian Harris Newmark recalled in his Sixty Years in Southern California that Sanchez was one of the "prominent Mexican politicians" who made "flowery stump speeches" to a group of "docile though illegal voters, most of whom were Indians," who had been literally corraled by backers of Thomas H. Workman who was running for county clerk and who swung them over to vote for the Democratic candidate instead of for Workman.His stand against the bandits gained him political support from the recently arrived American settlers that resulted in his election to the Los Angeles County Board of Supervisors in 1857, 1858 and 1859.[4] On December 9, 1863, Sanchez was taking a man who had been convicted of murder to the vessel Senator, lying off the Wilmington, California, harbor when a group of vigilantes seized the prisoner and lynched him, throwing his body overboard weighted with rocks they had brought with them.[4] The Sanchez family is remembered in their adobe home in the western foothills of the Verdugo Mountains, a landmark now owned and maintained by the city of Glendale, California.After Tomas died in 1882, his wife, Maria Sepulveda, sold 100 acres, including the structure, to Andrew Glassel for $12,000, and then moved to the Los Angeles Plaza neighborhood.
