The glamorous mum-of-one, from the city of Ciudad Obregon in Mexico, was reported as missing by her parents on August 19.
Her body was one of seven found in a shallow grave in the area of Canal Bajo, in Cajeme, on September 20.
There may be at least five other bodies to be added to the total, according to reports.
But prosecutors have not yet confirmed the extra deaths.
She was initially identified when relatives identified clothing found in the mass grave as belonging to her.
DNA analysis has now confirmed the identity.
When she vanished, her brother Juan Carlos Alvarado Rivera posted photographs online appealing for somebody to help find her.
He wrote: “You’re going to come back sister you’re a very good woman, you don’t mess with anyone, you’re a super mom you’re going to come back because this is all a misunderstanding and because of the love you have for your son.”
When news of her death was then confirmed, her brother posted another message.
The grieving brother said: “Fly high sister.
“I’m going to miss you so much my sister, my life partner, see you soon to be back together, my Queen.”
Police also found the remains of six other bodies in the grave including three men, two women, and a victim whose gender has not been established yet.
Officers have arrested three suspects since the grave was discovered.
Forensics experts are analyzing the bodies and the grave site and have already confirmed that one of the victims was her.
The other remains have yet to be identified.
The victim’s family has yet to release a statement.
The investigation is ongoing.
