OK - Ashley Lorene Parnell, 25, is accused of physically abusing 23-month-old Skyler Roininen by slamming his head into an object March 27, causing a 7.87-inch fracture to the toddler's skull.
The baby sustained brain swelling and died the following day. An autopsy report listed the cause of death as blunt head trauma. Skyler was the son of Parnell's boyfriend.
Parnell was arrested Monday. Interviews with Parnell, the boy's father, Robert Roininen, and Parnell's grandmother, Nina Fries, failed to reveal how the child's fatal injuries happened.
Parnell, however, told police that she smoked marijuana before going to sleep the day the toddler was found unresponsive. Police also discovered marijuana in Parnell's bedroom.
Authorities found the floor of the toddler's bedroom to be "filthy" and covered with what appeared to be rodent droppings. Evidence of rodents also was discovered in the child's bed.
Parnell told police Skyler was fine the evening of March 26. At about 5 the following morning, the father reportedly checked on the boy after hearing him crying. After the child became quiet, the father entered his bedroom, and the toddler began crying again.
Parnell then checked on the toddler, finding him sitting up with eyes wide open and arms held high. She changed the baby's diaper and rocked him to soothe him.
After going to the kitchen to get a drink, she checked on the child again and noticed that his eyes were half-open and that he was breathing strangely. Picking up the "limp" child, she carried the baby back to her bedroom and told the father to call 911.
Parnell told police that after getting up to use the bathroom and check on the crying child, everyone else in the house was asleep. Roininen said he didn't see or hear anything happen to his son.
