I think this ending is the least rushed of the three stories you've posted. Something to consider is the order you present the information. It sounds like Kyle is being interrogated right after the incident, then we're told about Jake's cause of death and some of the police's conclusions. It takes time to have the autopsy performed, determine cause of death, and draw conclusions about what happened. So to me, it makes more sense to include that later in the epilogue, after the interrogation. That said, I feel like everything was wrapped up and I'm not left with questions. I'm relieved Kyle made it out ok. Thanks for sharing your work with us
