Caught Red-Handed...
Sometimes the circumstances of a criminal case are such that the defendant will have an impossible time of trying to act like he or she did not commit the crime for which the defendant is charged. Take, for example the case of Marcelo Ochoa-Sanchez, who stabbed his wife to death in front of numerous eyewitnesses because he believed she was having an affair. In fact, Sanchez was so undisturbed by the thought of being detected while committing the crime that he stabbed his wife in the middle of the street, went home to switch knives, and came back to stab her some more, eventually killing her. He has been charged with first-degree murder.
It's awfully hard to deny the commission of a crime when you are spotted in broad daylight, on camera, or by several eyewitnesses performing the acts of which you are accused. In such instances, assuming there is no way to keep the evidence out of court, a defendant's best option may simply be to admit guilt in the matter and focus his or her efforts toward the sentencing aspect of trial.
The defense of insanity is one that is raised often when an individual is seemingly caught red-handed in the commission of a crime. Very often, this defense fails unless presented effectively. In the case of Mr. Sanchez, an insanity defense may prove successful, since, as the article cited above references, he thought his wife was cheating on him at the time he committed the offense because she used her mobile phone to contact individuals that he assumed were listed under code names. However, every situation is different and an insanity defense may or may not be appropriate depending on the circumstances.
