A Pennsylvania man has been charged in connection with a 1993 sexual assault after investigators linked his DNA to the victim using a public genealogy website, authorities said.

Jeffrey King, 54, of Coatesville, was busted on Oct. 3, some 26 years after a 22-year-old woman was attacked as she walked along a sidewalk in Newark, Delaware.

The victim reported the sexual assault, telling investigators that the suspect also fled with her clothes and personal belongings, but no arrests were made, Newark police said Tuesday.

The victim was taken to a hospital for a sex assault examination and a composite sketch was handed out to nearby residents, but King was never identified as a possible suspect, police said.

That changed in late 2017 when Newark police reopened the case as part of Delaware’s Sexual Assault Kit Initiative, leading a detective assigned to the case to send the sexual assault kit to a private lab to identify possible DNA samples.

Evidence in the kit indicated a male DNA profile, but King wasn’t identified at the time because his DNA was not in the FBI’s national DNA database, police said.

The sample was sent to a second lab in Virginia that specializes in DNA phenotyping — the process of predicting a person’s physical appearance and ancestry from unidentified genetic data.

The DNA profile — which contained predictors on the subject’s ancestry, as well as the color of the man’s eyes, hair and skin — was referenced against known DNA samples in various databases, including a public genealogy website, police said.

King, who was 28 years old at the time and had connections to Newark, was among the list of suspects provided by Parabon Nanolabs. Detectives collected an item with King’s DNA on it that he threw away as they conducted surveillance on him beginning in August, Newark police said.

“We watched him discard it and we took that item, brought it our Division of Forensic Science and they were able to extract DNA from that item,” Newark police Lt. Andrew Rubin told reporters, according to WCAU.

King, whose DNA profile matched the sample taken from the suspect in 1993, was taken into custody in Pennsylvania without incident before posting bail and later surrendering to Newark police.

King, who was charged with two counts of unlawful sexual intercourse, has since been released after posting $50,000 cash bail, the Delaware News Journal reports.

Police announced King’s arrest Tuesday alongside Delaware Attorney General Kathy Jennings, who said the crack in the 26-year-old case shows that the initiative to analyze previously untested rape kits is working.

“It illustrates that there are police and prosecutors who are working towards justice every day, even in cases that may have seemed cold,” Jennings said. “And it tells survivors that when they come forward to report a rape or sexual assault, we will do everything we can to support them and seek justice on their behalf.”
