A Rhode Island murder case from 1985, unsolved for over 40 years, may now be resolved due to new DNA technology and evidence collection. On October 6, William “Billy” Morton was arrested and charged with first-degree murder in connection with the death of Hillary Hellewell.
Breakthrough in Cold Case Investigation
Hillary Hellewell was found dead on May 19, 1985, in Newport, Rhode Island. Investigators had long suspected Morton of involvement but required DNA evidence to establish a connection. In August, an investigator obtained a potential DNA sample from Morton at a concert.
The investigator followed Morton to a theater, where Morton purchased popcorn and bottled water. When Morton and his fiancée left without their trash, the investigator collected the water bottle. DNA from the bottle matched samples found on Hellewell’s body, according to official reports.
Details of the 1985 Incident
Hellewell’s body was discovered by two young men on a sidewalk along Anthony Street in Newport. She was dressed in white pants and a sweater, but without shoes. The medical examiner reported strangulation as the cause of death, classifying it as a homicide.
Further examination revealed biological evidence indicating sexual contact. Despite initial investigations, including reviewing potential male suspects close to Hellewell, Newport Police could not identify a suspect.
Revisiting the Case
State officials revisited the case in 2004, hoping advancements in DNA technology could offer new leads. The DNA profiles from the case were entered into the FBI’s CODIS database. Fast forward to 2023, a newly formed Cold Case Unit re-evaluated the evidence with updated technology, focusing on Morton as a suspect.
The investigation revealed Morton’s conviction for a violent sexual assault in Newport, occurring shortly after Hellewell’s death. This increased suspicion and provided direction for investigators.
Gathering New Evidence
In August, Investigator Michael Nayor from the Rhode Island Office of the Attorney General monitored Morton and obtained DNA from a discarded water bottle. This DNA evidence was consistent with DNA found on Hellewell’s clothing and surrounding evidence.
Current Legal Proceedings
Following the DNA match, Morton was arrested on October 6 by officers from multiple agencies. He was charged in Rhode Island District Court and is currently detained without bond. Attorney General Peter F. Neronha confirmed that the case is proceeding to a grand jury, with a status conference set for October 20.
The case highlights how modern technology and persistent investigation can address longstanding unsolved crimes.
