Erica Reschke, 30, and Brandon Hobbs, 34, of Cassopolis, Mich., were charged earlier this month in connection with Chloe's death.

At the time, the prosecutor's office only revealed the charges, but not the reason for the charges.

Chloe's preliminary cause of death was ruled natural due to a bowel obstruction. Toxicology tests showed she had high levels of methamphetamine in her system. The coroner could not rule out methamphetamine toxicity as a contributing cause of her death.

Investigators with the Elkhart County Homicide Unit found Reschke and Hobbs took Chloe and her 9-year-old sibling to a house in Elkhart County the night of June 9. Both children required intensive supervision because they both had special needs.

Investigators say Chloe ingested meth Reschke had taken to the home.

Reschke has been charged with two counts of neglect of a dependent resulting in death and one count of neglect of a dependent. She could be sentenced to up to 42.5 years in prison if convicted.

Hobbs has been charged with two counts of neglect of a dependent. He could be sentenced to up to 2.5 years in prison if convicted.

Their trial is scheduled for May 6.
