The U.S. Marshal Service recently announced a $5,000 reward to anyone who aided in the direct arrest of Fields and Diaz, who were wanted in the death of a 4-year-old girl, police say.
Fields is a habitual domestic violence offender with two prior incidents, according to court records.
Gabby's father and grandparents stated that Diaz had custody of the 4-year-old girl when she died.
Gabrielle had obvious severe burns about her extremities and was taken to St. Joseph Mercy Hospital, where she was pronounced dead.
The medical examiner found evidence on the girl's body of multiple traumatic injuries, as well as signs of battered child syndrome - multiple injuries, multiple sites and multiple ages, according to local police.
According to the police, the duo is believed to be driving in a black 2002 Chevrolet Cavalier with the MI license plate DTR 1854.
MI police charged Candice Diaz and Brad Fields in the death of Diaz's four-year-old daughter. Diaz told them Fields punched her several times in the head and smashed her cellphone, according to a Sumpter Township Police report.
Gabby was found at the home of her mother and her partner January 1, according to the Daily Mail.
Police found Gabby unresponsive on January 1 at around 10:45 a.m., inside her family home in Sumpter Township.
Mourning the little girl's death Barrett's father, Kyle Barrett told Fox 2: "She didn't have to pass the way she did but I hope we get justice for her really soon".
The suspects were arrested by U.S. Marshals in Macon, Georgia with help from the Lowndes County Sheriff Department, said Sumpter Township Police Chief Eric Luke in a news release.
"She was a ball of joy", added Deborah Barrett, Gabby's grandmother.
Gabby's family has set up a GoFundMe account for funeral costs. "She would run around the house when we had her, always with a big ol' smile on her face". Diaz pleaded guilty to weapons offenses and was given a probationary sentence.
Meanwhile, Diaz and her boyfriend, Fields, fled the scene and are now on the run.
