LAKE PARK — A Michigan couple accused of killing a 4-year-old girl was arrested on Interstate 75 in Lowndes County Tuesday, according to the sheriff.

Around 3:30 p.m., Lowndes deputies, together with deputies from Hamilton County, Fla., and the U.S. Marshals Service, stopped a Chevy Cavalier on I-75, according to a statement from the Lowndes County Sheriff’s Office.

The investigation began after police responded to the home in Sumpter Township, Mich., and the child wasn’t breathing.

She later died at the hospital. The coroner ruled the death a homicide due to signs of battered child syndrome.

Both Diaz and Fields are being charged with murder. Lowndes County Sheriff Ashley Paulk said he wasn’t aware of any other charges at the moment.

Both were taken to the Lowndes County Jail, where they are awaiting extradition to Michigan, according to the statement.

They did not resist and no weapons were found in the car, Paulk said.
