A former Border Patrol agent who escaped from custody was sentenced to two years in federal prison. U.S. District Judge J. Lawrence Irving told Martin Nava, 27, of Chula Vista that he felt the escape charge was more serious than the charge that Nava was originally held on--transporting two Mexican women into the United States illegally. Nava was fined $1,000 for that offense. He was arrested June 25 after fellow Border Patrol agents stopped his car on a farm road about six miles east of the San Ysidro border crossing. Nava was off duty and out of uniform at the time. Nava's attorney said Nava was romantically involved with one of the women at the time and panicked after his arrest, prompting him to escape.
