The First 48

In Birmingham, AL, a woman, her son and her young niece are stabbed more than 75 times then set on fire inside their apartment. Investigators zero in on the victims' relative. But at trial, the defense claims the suspect's IQ is too low to qualify for the death penalty. It would be up to the prosecution to paint a gruesome, vivid picture of this brutal crime to secure a capital murder conviction and the ultimate punishment.
