A La Mesa man who works as a security guard has been jailed in Tijuana for almost three months after he says he mistakenly drove across the border with a gun. Rodney Dantzler Jr. has a license to carry a firearm but guns are illegal in Mexico. Dantzler said he drove across the border by mistake during rush-hour traffic on March 23. The 28-year-old works as a security guard and was carrying his handgun and ammunition in the trunk of his car. His mom, Jackie Anderson, said her son simply missed his exit. “He thought he was going to be able to make a U-turn. Then once he got over there, his whole world is upside down,” said Anderson. Dantzler was driving to Chula Vista to show off his new car to a friend, the mother said.
