A federal judge has delayed a hearing for three Lancaster men facing weapons charges in a case linked to last month's fatal shooting of a U.S. agent in Mexico.
Two of the suspects appeared in a Dallas courtroom Tuesday, but the judge postponed the hearing until later in the week at the request of defense attorneys.
Two U.S. Immigration and Customs Enforcement agents were shot, one fatally, on a highway in San Luis Potosi last month. Mexican authorities say a regional boss for the Zetas drug gang accused in agent Jaime Zapata's slaying has been captured.
U.S. authorities say the gun used in the slaying was bought by one of the three Lancaster men, who were arrested Monday at their homes.
