A single yellow sock found 28 years ago in the apartment of a man whose girlfriend had been discovered dead is now "a key piece of evidence" in the murder case against him. Theodore Dill Donahue immediately became a person of interest in Denise Sharon Kulb's killing after her badly decomposed body was found covered in clothing—including one ribbed yellow sock—in woods 30 miles southwest of Philadelphia in November 1991, reports the Washington Post. Relatives recalled they'd last seen Kulb, a heroin addict, fighting with Donahue, then 24, outside a bar on Oct. 19, in the days after she'd moved out of his apartment. The pizza delivery man, who initially denied that account, allegedly admitted to parts of it when police, their interest piqued by his "TedBundy1967" email handle, re-questioned him in 2015. Then police turned to the sock.
Photo-enhancing technology confirmed the sock found in Donahue's apartment in 1991 matched the one found with Kulb's body, Anthony Voci of the Philadelphia District Attorney's Office said during a Tuesday press conference, per the Post, which notes police failed to say why the socks weren't matched decades ago. Voci said Donahue had also told acquaintances details of the murder that weren't publicly known, including that Kulb was found facedown after being strangled. Donahue also allegedly claimed that his girlfriend was "not coming back." Arrested Tuesday, the 52-year-old faces charges of murder, evidence tampering, abuse of a corpse, obstruction of justice, and making false reports to police. "He denies the charges, and we will dispute it in court," lawyer R. Emmett Madden tells the Philadelphia Inquirer. Donahue is being held without bond. (Read more murder stories.)
