Carolyn Byington was found murdered in her Hunters Glen apartment on June 10.

Authorities are continuing to investigate the murder of a 26-year-old Plainsboro woman and are now working with federal law enforcement to solve the crime.

The body of Carolyn Byington was discovered inside her Hunters Glen apartment by police at 6 p.m. on June 10, according to a statement by Middlesex County Prosecutor Andrew Carey and Plainsboro Police Chief Fred Tavener.

Officers had been dispatched to Byington’s apartment following a request by her coworkers to conduct a wellness check. They became concerned after she left for her lunch break and never returned. She worked as a senior associate in project management at Engine, a marketing and advertising company in Carnegie Center in West Windsor.

Her death was ruled to be a homicide later that evening following an autopsy by the Middlesex County Medical Examiner’s Office. Authorities have not released further details of the crime, including the manner of Byington’s death.

Andrea Bolton, spokesperson for the prosecutor’s office, said on June 25 that authorities are still “aggressively seeking” Byington’s killer, but she could not release any additional information because the murder is still actively under investigation.

The latest update on the case was a statement from Carey on June 25. “The investigation into the homicide of Carolyn Byington is active and continuing,” he said. “Detectives with the Plainsboro Police Department and the Middlesex County Prosecutors Office have dedicated the resources necessary to pursue all leads, and are using all available investigative and forensic techniques to solve this murder.

“In this regard, we are also working directly with federal law enforcement agencies. We continue to offer our sincere condolences to the friends and family of Ms. Byington,” Carey said.

Meanwhile, a number of news outlets have reported that neighbors reported hearing faint screams coming from the apartment on the day she was killed, along with what sounded like furniture moving. They said they didn’t see anyone leave. No one called police to report what they heard.

NJ Advance Media reported on June 14 that two sources familiar with the investigation said that Byington had been drawn home for some reason, and she was apparently attacked once she entered her apartment.

Byington was a graduate of Ridge High School in Basking Ridge and earned a bachelor’s degree in international affairs/anthropology and sociology (double major) from Lafayette College. She also studied in Japan.

Engine released the following statement shortly after Byington was killed. “Engine is in mourning over this shocking, senseless tragedy. Carolyn was deeply cared about by her colleagues.”
