Watch out for the caffeine crazies!

Could consuming too much caffeine make someone crazy enough to commit murder?

Lawyers for Woody Will Smith, whose murder trial in Newport, Ky., starts today, plan to argue that the 33-year-old defendant had ingested excessive caffeine before he allegedly strangled his wife and so was temporarily insane, according to The Associated Press.

Shannon Sexton, the defense attorney, plans to state that Smith was not even able to form the intent of committing a murder, although prosecutor Michelle Snodgrass will say that Smith tested negative for substances containing amphetamines after the killing.

Smith is charged with killing his wife, 28-year-old Amanda Hornsby-Smith, in May 2009, by strangling her with an extension cord.
