Prosecutors plan to rest their case today in the perjury trial of a Mexican internal security officer accused of lying to the federal grand jury investigating the kidnaping and murder of U.S. drug agent Enrique Camarena.

Wednesday’s witnesses included an FBI agent who testified that a hair found at the Guadalajara house where Camarena was interrogated and tortured last year appeared to match that of Mario Martinez Herrera.

Martinez, though not accused in the drug agent’s death, is charged with lying to the grand jury by denying he had ever been in Guadalajara. Earlier, a Mexican lawyer, shot and paralyzed for cooperating with the Drug Enforcement Administration, testified that he saw Martinez in the Mexican city on six occasions in 1984.
