A man and a woman in their 20s were tortured and hanged from a pedestrian bridge in a border town for denouncing a drug cartel on Internet forums and blogs, CNN reported Wednesday.

The incident took place in Nuevo Laredo, a city of 400,000 just across the Rio Grande from Laredo, Texas. Two notes referencing online activity were discovered at the crime scene, one of them tied to the leg of the male victim.
