GREENVILLE, SC (WSPA) – Greenville Police Department officials said a forensic laboratory report from the South Carolina Law Enforcement Division found that a woman charged in the homicide case of Julie Valentine was identified as the child’s biological mother.

According a police department news release, the analysis of Brook Graham’s DNA concluded that Julie Valentine’s DNA profile is consistent with being the biological child of Brook Graham Willis — also known as Brook Graham.

“It is approximately 4.5 quadrillion times more likely to see these genetic results if Brook Graham and (father’s name redacted by GPD) are the biological parents of Jane Doe than if two random unrelated individuals are the biological parents. Given the genetic evidence, greater than 99.99% of randomly tested individuals would be excluded as the possible parents of Jane Doe,” from the report.

The findings will now be given to the 13th Circuit Solicitor for the purposes of prosecuting Graham, police officials said.

Graham was arrested last week and charged with homicide by child abuse, according to jail records.

The infant’s body was found Feb. 13, 1990 by a man picking flowers to give his wife for Valentine’s Day. 

The baby was in a cardboard box, covered with bedding and rags, among garbage in a field.

Greenville Police Chief Miller said investigators determined the infant was full-term. It’s believed she was born three days before she was discovered. 

According to affidavit, Graham and her boyfriend, the child’s biological father, lived in close proximity to where the infant was abandoned.
