There's speculation about his possible communication with BTK, it's not confirmed. At least not that I've heard. But he was studying at some point, the BTK case. Also BTK's first murder was a party of 4, so they think he may be mirroring the BTK as homage. BTK's daughter is doing interviews and crying on TV, I'm sure it's a paid gig. But, she's feeling guilty about the possibility that her father inspired this quad kill. (I think 10 to Life on YouTube did a episode about this topic, crime podcast)

I found her but not which video yet. https://www.bitchute.com/channel/probablyalexandra/
Not 100% sure of her credibility but her series Programmed is intriguing.
