Lethal ALS

"The defense’s primary expert, Dr. Doug Tucker, Raymond said, is not an ALS specialist, and diagnosed Steele with major neurocognitive disorder in order to avoid making a different diagnosis, frontotemporal dementia, because that diagnosis would have required evidence of bad behavior by Steele both before and after the murders, and there was none.
She called it a 'matter of semantics, a shell game.'
Raymond also said that the defense’s case 'vilifies people with ALS,' and implied that the 10 to 20 percent of people with ALS who also have frontotemporal dementia (FTD) could commit violent acts like Steele."
