A judge released the security video of Anthony when she sees a TV report that a child's body had been found near her Florida home. The remains turned out to be those of her daughter, Caylee.
In the black-and-white video, the quality of which resembles a convenient store surveillance camera with no audio, Anthony doubles over with her hands in her lap. Rising back to an upright posture she appears to be breathing heavily at times, though it's hard to tell because of the video's quality. She repeats this process a few more times. An attorney later came in to console her.
The tape was kept sealed during her murder trial.
Anthony was acquitted of killing her daughter but convicted of lying to police. She is somewhere in Florida serving a year of probation on a separate check fraud conviction. Authorities are keeping her whereabouts confidential for her safety.
Anthony's acquittal caused a national uproar, with people expressing their displeasure with the verdict both publicly and through social media.
