鈥淣othing can prepare you for what it feels like to lose both parents instantly at the same time,鈥� Jake Reiner writes. 鈥淚t鈥檚 too devastating to comprehend. I still wake up every morning having to convince myself that, no, it鈥檚 not a dream. This truly is my living nightmare.鈥�

The long post makes only two fleeting mentions of his younger brother Nick Reiner, who has been charged with killing their parents, and he does not use Nick’s name.

鈥淪ure, any loss of a parent is devastating, but nothing compares to losing both of them at the same time and, on top of that, having your brother be at the center of it,鈥� Jake Reiner writes toward the end of the post.

鈥淲e loved the Dodgers more than anything,鈥� he writes. 鈥淲e went to so many damn games.鈥�

He calls his mother “the engine, the backbone, and the heart of our entire family. And not just our immediate family. She was the reason behind why we spent time with our extended family too.鈥�
