Johnson's Family Testifies in Murder Case
Johnson killed three Casey's General Store employees with a hammer 12 years ago.
The Missouri Supreme Court overturned Johnson's two previous death sentences because of questions about his illegal drug use and mental capacity.
Now, his lawyer wants Johnson declared mentally disabled to avoid another death sentence.
Johnson's relatives testified Tuesday, saying he was abused as a child.
"I expect the state to wrap up with their rebuttal evidence," defense attorney Timothy Cisar said. "They will have some people coming insaying, essentially, the opposite of what we're saying, that he's notmentally retarded and along those lines."
The defense will resume its case Wednesday morning, when it calls three experts on drug use and mental disabilities to testify.
