United States Border Patrol agents say they arrested a US citizen Monday who tried to cross into the US illegally by driving his truck through the Rio Grande. Agents say they saw the man walking along the south side of the border barrier near Fonseca Drive and Cesar E. Chavez highway. Agents say he was taken into custody for illegal entry. When agents checked his records, they discovered he had an extensive criminal history and an active warrant out of Wichita, Kansas, for murder.
