I guess you mean the autopsy evidence might not prove BL is the killer of GP. But there is really strong circumstantial evidence against BL. He was her long-time companion and driver. They lived together in Florida and there are plenty of pics of them together on Instagram. The van was parked close to where she died in a place away from other campers. People saw the van parked there, which is how LE knew where to search and discovered the body. Even without the Moab and Merry Piglets incidents showing BL's anger issues, a jury might convict just based on BL's proximity to the body and opportunity.to kill her. Add in the fact he drove away without her, which meant he knew she was either dead or missing. So either he killed her himself or didn't care that someone else might have kidnapped or hurt her. He never reported anything about it to police in Wyoming, which makes him seem guilty. A good defense attorney might come up with some scenarios to spin, but that doesn't mean a jury will buy any of it.
