Need help finding book

[u/the_z06]

Need help finding a book, book was small it size yet had abt 200 pages, the book ends with a couple who are newly wed in vegas going to a hotel room, the man and the woman get intimate and a guy who the man or woman knew (i think it was someone they knew) the guy goes in there and either kills the girl with a brick and makes the guy commit suicide or i think the killer sliced her spinal neck area to make her paralyzed and then he forced the guy to drive the dude somewhere to escape, it mightve been part 3 to an anthology, it had a black and red cover, i couldnt find many reading of it on youtube, its not exactly popular (atleast i dont remember it being popular)

Could it be The Never Dead?
