Declan was placed in protective custody on Jan. 9, 2006, the same day he was hospitalized for dehydration and bruising to his bottom, thigh, back and right shoulder, police reports show.
The boy then was 3.
On Saturday, emergency workers responded to a report Declan fell 3 to 4 feet in his closet and hit his head at 2001 Hardy Drive, according to an Edmond Fire Department incident report.
"Declan Stewart was admitted to Children's Hospital ... Declan was diagnosed with a subdural hematoma,” according to the DHS records.
"In addition, Declan had a large reddish purple bruise on his left arm, above his elbow on the outside of his arm. Declan also had ... broken blood vessels on his stomach, bruising on the insides of both knees as well as swelling, a laceration on the back of his head, a bruise under his left eye, a bruise in his left arm pit.
"Declan further had a bruise on his left scrotum,” the DHS records show. "This bruising did not appear to be new. ... Declan sustained similar injuries when he was placed into protective custody ... He was home with his caregivers one month before he sustained fatal injuries.”
Clancy's three daughters were visiting their father for the weekend, according to the records.
The girls' paternal grandparents were given guardianship of them in June 2005, according to court records.
The grandmother, Susan Clancy, "said Declan was not abused by her son but somebody hurt him,” according to the DHS reports.
No one has been arrested.
Glynda Chu, Edmond police spokeswoman, said Wednesday afternoon, "We're not investigating Janet Stewart and Marcus Clancy. We're investigating the circumstances surrounding the death of Declan. We are waiting to determine if the death was a homicide.”
Prater said Wednesday, "We believe the incident is suspicious. We are awaiting medical examiner's reports and Edmond police department reports.”
DHS officials have declined to discuss their involvement in the case because of privacy laws. They can reveal some limited information if someone is charged.
Clancy currently is on probation after he pleaded guilty to marijuana possession, records show.
The boy's aunt said when she first got Declan last year, he clung to her.
She said she didn't know if it was because he had been abused or because he had been in a shelter.
More recently, he was "like any other happy kid,” she said.
"He loved being around people. He loved Spider-Man and candy. He was very energetic,” she said.
