GAS CITY, Ind. – The stepmom of a missing 10-year-old in Gas City is accused of strangling the girl.

Police arrested Amanda Carmack, Skylea Carmack’s stepmother, Wednesday morning around 4:30 a.m. in connection with the girl’s death. She faces preliminary charges of murder, neglect of a dependent resulting in serious bodily injury, strangulation, and domestic battery resulting in serious bodily injury.

The four-day search for Skylea came to an end around 3 a.m. Wednesday morning. Police found her body in a shed behind her Gas City home. She was hidden inside a plastic trash bag.

Skylea’s father, Kevin Carmack, told FOX59 he left Skylea at home with Amanda and six other children when he went to work on Saturday.

Police say evidence shows Amanda strangled her between 4:30 p.m. and 6 p.m. Amanda called police to report her missing around 9 p.m.

An autopsy confirmed Skylea’s cause of death was asphyxia by strangulation, and the manner of death was homicide.

Police say a “conglomerate of evidence” led them to arrest Amanda, and they believe she is the only person involved in the murder. They have no other suspects at this time.

The six other children who were in the home are now with Child Protective Services.

“There’s no rationale” for killing a 10-year-old girl, Indiana State Police Sgt. Tony Slocum said. “That’s just cowardice.”
