A desperate manhunt is underway Tuesday morning to find a woman and her boyfriend in connection with the death of a 4-year-old girl.
Diaz and Fields are facing murder, torture and child abuse charges.
They found the girl unresponsive with "obvious" severe burns on her arms and legs.
Severe burns covered the little girl's extremities, according to police who responded to a 911 call at the Sumpter Township, Mich., mobile home park, just before 11 a.m. on January 1.
The Washtenaw County (Mich.) Medical Examiner ruled the death a homicide with evidence of multiple traumatic injuries and battered-child syndrome - meaning she suffered multiple injuries, at multiple sites, at multiple ages.
A manhunt is underway for Diaz and Fields, and they are believed to be driving a black 2002 Chevy Cavalier bearing MI license plate DTR 1854, pictured below.
The couple face charges of felony murder, second-degree murder, first-degree child abuse and torture in the death of Gabby Barrett.
The child since identified as Gabby Barrett, was discovered with scald wounds all over her body shortly before 11am on January 1 at her family's mobile home on Greenmeadow Drive in Sumpter Township. Fields fled the scene, but was later picked up on domestic violence charges.
"She didn't have to pass the way she did, but I hope we get justice for her really soon", Barrett said.
The investigation began after police responded to the home in Sumpter Township and the child wasn't breathing. "I know we may not have a lot of information at all, but, it just hurts", said Barrett.
"She was a ball of joy", added Deborah Barrett, Gabby's grandmother. She always had a smile on her face, loved to play.
Police records paint a chaotic picture of life inside the couple's home, where Fields was accused in 2016 of assaulting Diaz, shooting her dog and shooting himself.
She pleaded guilty to both counts and was sentenced to three days in Wayne County Jail and two years probation.
A GoFundMe page has been set up by the victim's kin to raise funds for her funeral.
