Oklahoma City police say 22-year-old Brooke Phillips, who worked at a Nevada brothel that featured on an HBO reality series, was among four people found dead in a burning house earlier this week.
Oklahoma City Police Department spokesman Sgt. Gary Knight says Phillips and another pregnant women died of gunshot wounds.
Knight says the state Medical Examiner's Office identified Phillips and 22-year-old Milagrous Barrera on Friday. A man and woman also found by firefighters fighting Monday's blaze at a house in Oklahoma City have yet to be identified.
Authorities say the fire was deliberately set and that they are treating the case as a homicide.
Phillips worked at the Moonlite BunnyRanch and appeared in HBO's "Cathouse."
