I think there are a lot of reasons to think it was probably arms smuggling:
WITNESS: Following a hit man's rifle to Mexico
Tim Gaynor is a Reuters correspondent based in Phoenix who covers immigration in the United States and writes about crime and security along the Mexico border. In the following story, he tells how he traced a Kalashnikov rifle bought in Arizona to a mining town in Mexico where it was used by a drug gang in a battle with police and troops that killed 23 people.

PHOENIX (Reuters) - The agent raised the machine gun to his shoulder and let rip a deafening hail of shots that smacked through a bullet proof vest, punched holes in a car door and spat up a plume of sand in the levee behind.
Taking the plugs out of my ringing ears, I walked over the gritty desert firing range to look at the damage from the Kalashnikov.
The traffic of guns of this type from the United States to the warring Mexican drug cartels is the less-reported flip side of the drugs trade north from Mexico and South America.
I have covered crime on the U.S.-Mexico border for several years, and was trying to grasp first hand the devastating power of the weapons used in Mexican crime, the ease with which they are trafficked over the border, and the human cost for the Mexican authorities so often in the firing line.
"This is the type of fire power that we are seeing being trafficked into Mexico and arming the cartels," said Tom Mangan, a senior ATF special agent with the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, examining the debris from the firing and explaining the effects.
Last year, Mexican cartels murdered more than 2,500 people in an all-out war for lucrative drug routes to the United States worth billions of dollars. Many were shot using assault rifles readily and legally available in the United States, and trafficked to Mexico, where gun sales are banned.
Earlier, I had gotten into my pickup truck to follow the route of one semi-automatic Kalashnikov that was bought at a Phoenix gun store. It turned up a year later in a raging gun battle around the mining town of Cananea in northern Mexico that killed 23 people.
The rifle, like thousands of others, was bought in what they call a "straw purchase" -- where a third party is paid to buy guns to order for a cartel "gatekeeper" -- then driven over the desert to Mexico.
I crossed through the tiny border town of Naco, Ariz., where in 1916 troops under General John Pershing had pursued bandit-turned-revolutionary Pancho Villa into Mexico during the Mexican revolution.
A road sign near the adobe border garret read "Warning: Firearms and Ammunition Illegal in Mexico." I saw a Mexican immigration agent rearranging a few traffic cones on the road, but no one stopped me to ask for my passport, much less check the truck.
I could have had a case of rifles in the back.
It took less than an hour over a narrow, winding road to reach Cananea, where on May 16, 2007 armed assailants drove into town in a convoy. Once they had methodically set up roadblocks, they started the killing, shooting dead five police officers and two civilians.
The assailants kidnapped ranch hands and commandeered horses, which they used to escape into the western Sierra Madre mountains. Police and troops were in hot pursuit and killed 16 of them before the day was out.
I asked for directions to the police station to find out more about that day, which one man I spoke to referred to as the "matazon" or "big slaughter".
Law enforcement official Pablo Cesar Angel Ortega was wrapped up against the cold in his office. He put in a call to ask a superior if he could talk to a reporter about the "sicarios" or hit men. He nodded and then spoke softly about the day he called "historic".
Whether it is liberal U.S. gun laws, buoyant Mexican demand, or unchecked borders that are to blame for the slaughter, one thing was clear: the pain etched on Ortega's face.
"We lost five of our colleagues," he said of the day the guns thundered. "You have to imagine, it's a small town and that's hard to bear."
ATF agents work closely with Mexican authorities to staunch the flow of weapons south under Project Gunrunner, using a software program called e-trace to track guns from Mexican crime scenes to the dealers who sold them in the United States.
The ATF frequently seizes military-grade weapons headed for the hit men, including assault rifles, high-powered "cop killer" pistols and huge quantities of ammunition bought in gun shops and at gun shows from California to Texas.
"It doesn't matter what body armor you wear," said Mangan. "That round is going through the door, through the vest and right out the other side ... It's just like a hot knife through butter."
