A Rhode Island murder investigation that remained unsolved for more than 40 years may have reached a breakthrough after investigators recovered a discarded water bottle from a theater.
William “Billy” Morton was arrested Oct. 6 and charged with first-degree murder in the 1985 Newport killing of Hillary Hellewell.
Investigators say advances in DNA technology now link the 61-year-old Morton to the crime, nearly four decades after Hellewell’s death.

Over the years, investigators developed clues pointing to Morton as a possible suspect. To establish the connection, however, they needed a sample of his DNA.
According to court records, an investigator followed Morton in late August to a Rhode Island theater where he attended a concert by a Heart tribute band.

Investigators said Morton purchased popcorn and bottled water for himself and his fiancée. The couple left the concert before it ended, and Morton did not take his trash with him. An investigator then collected the discarded items as potential evidence.
Court documents state that DNA obtained from Morton’s water bottle matched DNA recovered from Hellewell’s body.

Morton was taken into custody Oct. 6 and is being held without bond.
The killing
Hellewell, 22, was found dead in Newport on May 19, 1985. Two brothers, ages 17 and 20, discovered her body at about 4:15 a.m. as they headed to work.
Her body was lying on a sidewalk along Anthony Street. She was dressed in white painter’s pants, a sweater and socks, but she had no shoes on.
According to Morton’s arrest warrant, Hellewell’s pulseless body was mostly “cold to the touch,” although some areas remained “slightly warm” when officers arrived.
A medical examiner determined that she died from asphyxia caused by strangulation. Her death was classified as a homicide.
Investigators found a bloodstain on the back of Hellewell’s white pants, along with a “heavily soiled” blue T-shirt near her head, the arrest warrant states.
Swabs collected during an internal examination found spermatozoa, indicating sexual contact, according to the warrant.
Hellewell was identified the following day after she was reported missing.

Friends and relatives told investigators that Hellewell had attended a gathering with friends in Newport the night before her body was found. Investigators were also told that everyone at the gathering had consumed alcohol.
Investigators learned that Hellewell had offered to walk home with one of her male friends, who’d become overly intoxicated.

He made it home. She did not.
The next day, he was still so intoxicated, he couldn’t give many details to police.
The men who were close to Hellewell at the time of her death were ruled out as being “potential donors” of the sperm, according to court records. But Newport Police were never able to develop a viable suspect.
At the time of Hellewell’s murder, DNA evidence was collected and preserved.
Resurrecting a cold case
The case was reviewed by state officials in 2004. They hoped new advancements in DNA technology could help.
During that review, DNA profiles for Hellewell and the suspect were entered into the FBI’s Combined DNA Index System (CODIS) database.
Then in 2023, the Rhode Island Attorney General’s office formed the Cold Case Unit (CCU), and Hellewell’s case went under review again.

With recent breakthroughs of technology used to evaluate DNA, the evidence was sent to a private lab.
That work brought a new lead into sharp focus. Suddenly, Morton was a suspect.
Investigators pinpointed Morton’s family line through the DNA found on Hellewell’s body. They later found Morton had been convicted in 1987 of a violent sexual assault in Newport 45 days after Hellewell’s death. The assault took place a couple miles from where Hellewell’s body was found, court records show.
Morton was sentenced to 20 years in prison. He spent seven years behind bars, and served out the remainder of his sentence on probation.
Date-night DNA discovery
After the new DNA evaluation, investigators collected evidence and conducted interviews. New clues led them to Morton.
They began to watch and trail him.
On Aug. 21, Michael Nayor, a senior cold case investigator with the Rhode Island Office of the Attorney General, followed Morton and his fiancee, the arrest warrant shows. They pulled into a Burger King before heading to a theater in Woonsocket, Rhode Island.
The investigator purchased a ticket to a show by Bad Animals, a Heart tribute band, and followed the couple inside. He watched as Morton bought popcorn and two bottled waters, the arrest warrant shows.
Naylor watched Morton sip his water throughout the show. And when he set the bottle on the seat next to him, Naylor took note, the warrant shows. .
When Morton and his fiancee left early, the bottle of water was left behind. Naylor seized it and submitted it for DNA testing.
The DNA profile from the water bottle “is consistent with the previously reported partial profiles” from the sperm stain on Hellewell’s pants, and a stain on the blue shirt found near her body, according to the Rhode Island Department of Health.
On Oct. 6, officers from multiple agencies visited Morton’s home at about 7 a.m., as he was leaving for his job as service technician at a Volkswagen dealership. He was charged with first-degree murder in the Rhode Island District Court Second Division.
The case will go to a grand jury, said Rhode Island Attorney General Peter F. Neronha. A status conference is scheduled for Oct. 20.
