Mexican authorities found at least 49 decapitated and dismembered bodies along a highway in a northern border state Sunday morning, officials said.
The remains were left along the road in Nuevo Leon state, between the cities of Monterrey and Reynosa.
A message written on a wall nearby appeared to refer to the Zetas drug cartel.
"This continues to be violence between criminal groups. This is not an attack against the civilian population," said Jorge Domene, Nuevo Leon's state security spokesman.
After lying dormant for months, Mitt Romney's record as a private equity executive returned to the forefront in the race for the White House Monday as President Barack Obama's re-election team launched an assault on the Republican's record in the 1980s and 90s in the form of a tough new campaign video.
The attack focuses on Bain's history at one company, Kansas City-based GST Steel. The Obama team portrays the firm as a victim of Romney's brand of capitalism gone wrong. A two-minute television ad running in Iowa, Pennsylvania, Ohio, Virginia and Colorado – all battleground states – features former GST Steel workers lamenting the fact that they lost their jobs following Bain's takeover.
"They made as much money off it they could," says Dale Soptic, who the Obama campaign says worked as a steelworker for 30 years. "They closed it down, they filed for bankruptcy without any concern for the families or communities."
Political analyst John Avlon joins Erin Burnett to discuss the new campaign ad on Erin Burnett OutFront, tonight at 7 p.m. ET.
The Romney campaign today has responded to the Obama video with a video of their own, dubbed "American Dream."
