Shortly after the incident, on June 27, Grassley and Rep. Bob Goodlatte, R-Va., the chairman of the House Judiciary Committee, wrote a letter to Jeh Johnson, the Department of Homeland Security secretary, to learn more about Sanchez, who, according to media reports, had been arrested three times in the months before the fire.
Sanchez [had been] placed under supervision and ordered to report regularly to immigration authorities, but he stopped reporting in August 2014.
But in January of this year, the Los Angeles Police Department arrested Sanchez on suspicion of domestic violence. He was arrested again in May and June on suspicion of drug possession. His most recent arrest was less than a week before he allegedly set fire to the Los Angeles building. He was released the next day.
According to the Times, the Los Angeles Police Department does not honor immigration requests from the federal government to be notified of a person’s release from jail unless a warrant is issued or a judge has vetted the request.
