Violet Szeleczky, spokeswoman for the Houston division of the Drug Enforcement Administration, said violence among rival cartels has spilled over from Mexico into the Houston area, The Houston Chronicle said Saturday.
"They are just killing themselves," Szeleczky said. "Who lost a load within a cell? Who disrespected who by doing this?"
Lt. Dan Webb of the Texas Department of Public Safety narcotics division said little can be done to prevent drug cartel violence from crossing from Mexico into parts of Texas.
"There are so many different reasons why they kill each other," Webb said, "a rivalry between two groups; or some boss says 'kill this guy, he pissed me off' or boyfriend-girlfriend stuff gets involved."
Jaime Zamora is currently on trial for allegedly masterminding a hit on a rival cartel member that resulted in the death of an innocent civilian, the newspaper said.
