Assuming he's still alive, which I believe he is:
The reserve has issues: temp, humidity, critters, mud, flooding, insects, LE, media--not a hospitable place for a fugitive with enough unpleasantness already in his life. Maybe an OK first day/night getaway, but once BL knew that people were looking for him there, I don't see him staying, especially if he was in touch with family.
We know he's been dependent on family for quite a while. I don't think he'd go solo now that he's in a crisis mode. Maybe he knows how to fish or something, but he's not an outdoorsman. He needs outside support, and cash, and IMO it's got to be coming from people close to or in his family. However, his nuclear family is now under a microscope. I think, despite what has been released by LE about GP's death, he/his parents have woven a tale that seems believable to others within their circle. So maybe other relatives are shielding him, someplace he'd just need a mask, hat and sunglasses to blend right in. Perhaps where the population is sparser than in FL. The Northeast is getting cooler--hat, scarf and glove weather is almost here. Look, Ma, no fingerprints!
