I am struggling to find information regarding Igor Lanis, but I suspect he went berserk due to pre existing mental issues how t his wife most likely destabilized him by being a bitch to him over politics. Rebecca Lanis claims her dad was interested in crap such as Qanon, and I personally suspect she was full of shit and is trying to blame her mother's death on the dissident right rather than mental illness as she appears to be a regressive leftist.
