Furious Seasons has a post on WWE wrestler Chris Benoit, who possibly may have taken Zoloft shortly before he committed the murder of his wife and child. The article on pwtorch.com that FS linked to refers to the possibility that Benoit's friend and doctor, Phillippe Astin III, may have prescribed the drug to Benoit on Friday, the day before he killed his wife.
There are definitely some funky mental issues behind Benoit's motives for killing his family, but it wouldn't surprise me if the Zoloft played a part in influencing him to do so. I recently mentioned Christopher Pittman who killed his grandparents in 2001 then proceeded to set their house on fire when he was on an adult dosage of 200 mg of Zoloft. He was 12. Stephany of soulful sepulcher commented that her daughter suffered from a similar problem while on 150 mg Zoloft:
Pittman was about the same age my daughter was then, and she was on 150mg of Zoloft a day, and that med changed her personality into a full blown all day raging person. She had to go inpatient to get off of it, and once off of it, she's never raged like that again. The Pittman story is very sad, as are all of the others associated with antidepressant use and teen violence. Columbine had Luvox, there's Accutane–it's beyond me how this can be overlooked in connection.
I wonder if there are other stories floating out there now about how Zoloft – an antidepressant – has caused similar behaviors. It'd be interesting to observe whether Zoloft causes hallucinations, delusions, and psychosis.
