(MOBILE, Ala.) -- Arrest warrants describe the horrific abuse two young children allegedly suffered at the hands of their father and his girlfriend, including stuffing one of the children into a suitcase for 14 hours, before the children were allegedly killed by their dad.
As the grim details surrounding the children's death surface, police have announced they believe they found the remains of three-year-old Chase DeBlase, allegedly dumped in the Mississippi woods by his father, John DeBlase, in March.
Police are also scouring woods in rural Alabama for the body of five-year-old Natalie DeBlase, who police allege was killed and discarded by her father in June.
The arrest warrant details bizarre punishments allegedly devised for the children. It charges DeBlase with allowing his girlfriend, Heather Leavell-Keaton, to create a night-long torture for Chase while the parents went to bed.
"Allowing Heather Leavell-Keaton (his girlfriend) to duck-tape the childs hands to the side of his legs, tape a broom handle to his back, placing a sock in his mouth and duck-taping it to his mouth, then making the child stand in a corner all night when they went to bed," the warrant says.
Police have not yet given a cause of death for Chase or Natalie, although they believe the abuse played a major factor.
"We have not determined cause of death," Assistant District Attorney Joe Beth Murphree told ABC News. "Remains found yesterday and the medical examiner is looking at remains at this time. Even if exact cause cannot be determine we believe homicide can still be proved."
According to police, Natalie was not spared the monstrous abuse doled out by DeBlase and Leavell-Keaton, his girlfriend since 2008.
A separate arrest warrant outlines that DeBlase allegedly allowed Leavell-Keaton to duck-tape Natalie's hands and feet before stuffing her in a suitcase.
"Duck-tape the child's hands and feet, place a sock in her mouth, place her inside a black suitcase and leave it inside a closet from 8 a.m. until 10 p.m.," the warrant says.
