Key Medical Evidence Turned Over in Shaken-Baby Syndrome Case

Key Medical Evidence Turned Over in Shaken-Baby Syndrome Case

Medill Justice Project sought records for a year


Medical records obtained by The Medill Justice Project.

The Medill Justice Project has obtained thousands of pages of medical records, including copies of CT scans and MRIs of an infant’s head, which the attorney for a Chicago-area day care worker says undermines her first-degree murder conviction.

At Jennifer Del Prete’s 2004-2005 trial, an emergency room physician testified the infant’s brain bleed—also known as a subdural hematoma—likely was up to a week old when she was brought to the hospital. The defense’s expert medical witness testified then the brain bleed was as many as 10 days old.

The newly-released medical records indicate the infant’s brain bleed was older—at a minimum 14 days—which could mean the bleeding could have started before Del Prete began caring for the infant at a Romeoville, Ill., home day care, according to her attorney, Patrick W. Blegen.

“We think the medical records, when combined with the testimony, are very significant because they show that the chronic subdural hematoma was at least two weeks old and likely older than that,” Blegen said. “The critical error was that the people who testified at the original trial at state court said that the chronic subdural hematoma [brain bleed] was seven to 10 days old.”

Evidence dug up by Medill Justice Project probe of day care worker’s murder conviction

The attorney for Jennifer Del Prete, a day care worker convicted of murder, said authorities failed to turn over “favorable evidence” to the prisoner, potentially violating her constitutional right to a fair trial.

In a motion filed in federal court, attorney Patrick W. Blegen cited a nearly decade-old police record, which he had not come across until it was published less than a week ago by Northwestern University’s Medill Justice Project.

Blegen, representing Del Prete in a recent hearing in U.S. District Court in Chicago, said in his filing that authorities had not furnished this document; it was a police detective’s letter to the prosecution’s expert medical witness in which the detective expressed concerns that the forensic pathologist who conducted the infant’s autopsy questioned whether the child was a victim of what is known as shaken-baby syndrome or abusive head trauma.

Charles B. Pelkie, director of public affairs for the Will County State’s Attorney’s Office, said in an interview for this article, “These are serious issues raised in the federal filing, and it’s taken very seriously by our office.” He said his office has ordered the case file from storage. “We’ll have to take a look at it and comb through it,” he said.

The Medill Justice Project has won a six-month battle for records in federal court after a judge granted access to brain scans of an infant whose death the organization is investigating as part of a former Chicago-area day care worker’s first-degree murder conviction.


Since last March, Medill undergraduate students in a class supported by The Medill Justice Project have been probing a 2002 case in which Jennifer Del Prete in Romeoville, Ill., was accused of violently shaking a 3 ½-month-old infant, causing fatal head injuries in what is known as shaken-baby syndrome. Del Prete, who was sentenced to 20 years in prison in 2005, maintains her innocence. Given advances in medicine and science over the past decade, the detailed medical images, including MRIs and CT scans, may provide new insight into how the infant died. Read the full story here.
