A Santa Rosa man accused of stabbing his father to death in their Rincon Valley home was suffering a drug-induced psychosis from taking his mother's prescription pills but was not mentally insane, according to a doctor's report released Monday.
Houston Herczog, 21, was in the grip of Adderall, a psycho-stimulant prescribed for attention deficit hyperactivity disorder and narcolepsy that also has a following among recreational users and has been labeled a "study drug" for its ability to keep people awake.
Reported side effects of Adderall include mood swings and aggression. A number of websites discuss "Adderall rage," a condition of becoming infuriated while withdrawing from the addictive medication.
Menlo Park psychiatrist James Missett examined Herczog last week and found he had been taking the pills. His 34-page report concluded the drug played a role in the attack but said Herczog was fully aware of what he was doing.
Three previous psychologists found Herczog was suffering schizophrenia at the time. The 2009 Santa Rosa High School graduate has pleaded not guilty by reason of insanity. Family members have urged that he be placed in a mental hospital instead of prison.
His lawyer, Karen Silver, said Monday that Missett's findings are wrong.
"All it shows is that if you get enough doctors, you will find one to go the other way," Silver said.
The District Attorney's Office declined to comment because they said it was an open case.
Missett's report comes as both sides prepare for trial. Jury selection is expected to begin this week and witness testimony is next week.
Herczog is accused of killing Mark Herczog, 63, in their Parkhurst Drive home after returning from a late night trip to the gym.
