But in this booming narcotics corridor on the Mexico border, those killings generally are the result of drug transactions gone bad, authorities say. Less common, and more disturbing, is the murder of a witness or informant whose testimony may be vital to nailing traffickers. This week, the battered body of a key witness in a federal drug trial turned up across the border in Reynosa, Mexico another sign to some that the drug trade is growing more violent. ``It's a very brutal atmosphere,'' said Mavis Dezulovich, a spokeswoman for the U.S. Marshal's Service, which runs the federal witness protection program. ``Just look at what you're dealing with.'' Although U.S. authorities have not confirmed that the informant was killed because of his impending testimony, drug agents admit they are concerned the slaying could scare off other potential witnesses. ``It doesn't help us,'' said Alonzo Pena, chief of the U.S. Customs Service office in Brownsville. He estimates that the majority of his agents' drug cases are developed with informants. ``There are always threats, but it's very rare that an informant has harm done to him,'' Pena said. ``When an event like this takes place, it doesn't enhance our position in cultivating informants.'' On Tuesday, the body of Hector Salinas Guerra, 42, was found in a grassy lot near a school in Reynosa, his arms and legs bound with tape. His head was indented with a deep groove, possibly caused by a pistol or bat, and his body was pummeled, resulting in multiple fractures, Mexican police said. A plastic bag, which police believe may have been used to suffocate Salinas, lay near his body, along with his beeper. Salinas was abducted Friday night from his family's secondhand clothing store in south McAllen. Four men in clothing bearing Mexican police insignias forced him into a truck at gunpoint and sped off, witnesses told police. Salinas was to testify this week in the federal drug trial of seven men accused of smuggling about 3,000 pounds of marijuana across the border. He was a key player in a sting operation that helped bring down the smuggling ring, authorities said. He agreed to help prosecutors after drug agents found several hundred pounds of marijuana in the back of his clothing store in April. ``It's possible he was kidnapped and killed to prevent him from testifying. But if he were involved in the drug trade, it could have been retaliation for previous actions,'' said Barry Abbott, who heads the McAllen office of the federal Drug Enforcement Administration. Federal authorities said several agencies, including DEA and Customs, provide protection to witnesses or informants if they ask. Salinas had not requested protection, Abbott said. The same day Salinas' body was found, his son testified in his place. Hector Hugo Salinas told jurors that he worked with his father and five of the seven defendants, repackaging and storing marijuana shipments in the back of his father's store. Jurors never learned about Salinas' slaying and prosecutors have declined to comment until the trial is over. The case went to the jury Thursday. Copyright Los Angeles Times
