He was born and raised in Las Vegas. Towards the end of Season two, his father Larry McCoy (John Terry) died and he inherited his construction company, McCoy Construction, and house, which he sold to purchase his current apartment. Establishing shots suggest his apartment is in the Turnberry Towers.

He is currently living with his girlfriend, Delinda, who is pregnant with their child. He was involved in an on-and-off relationship with his childhood friend, Mary. At one point, the two were even (technically) engaged. The show was narrated by this character for the first few episodes. In Season 5, Danny finally gets Ed's job and is now President of Operations for the casino.(wikipedia.org)
