Patton Oswald.

Wife was writing a book about the Golden State Killer. She was consumed by it. She was working overtime because she found some big developments. What was she digging on? Who was she digging on? Did she stumble into something much bigger than she intended? Was she about to spill the beans on a much larger sex crime network?

“We learned today the combination of drugs in Michelle’s system, along with a condition we were unaware of, proved lethal,” he said.

The actor explained that the blockages proved fatal when combined with the medications Adderall, Xanax and fentanyl.

Golden state killer found in DNA database. There were others working on the same case but now there is nothing to dig for since it's all wrapped up. "Nothing to see here." (((They))) didn't want others to stumble into the same thing so someone was offered up as a patsy.

Patton is a major loud voice when it comes to shit talking POTUS. Killing her was a 2-for-1. Silence 1 voice for concealment and bring another person under control.
