No big surprise. With previous domestic violence incidents I am sure he was court-ordered to get counseling and what do you get in counseling? Standard prescription is an antidepressant which increase serotonin. And what is serotonin? It is what LSD & PCP mimic to produce hallucinations. And according to a study done in 1996 at the University of Southern California they found that serotonin is the key to human violence. So once these drugs are added to the mix this is how you often settle disputes when you hit a toxic level! Hopefully an investigation into that aspect will be conducted.
It is hardly the first suicide or murder/suicide involving a plane. Remember the Germanwings co-pilot on antidepressants who flew 150 to their deaths when he took over the plane & flew it into the side of the Alps? He was switching antidepressants due to the drugs affecting his vision just like the elderly Russian immigrant who killed my good friend Don Thomas in the Family History Library shooting. The poor man had no idea how dangerous it can be to make any abrupt change in dose of an antidepressant, up or down.
