The medical examiner’s office in Boston, Massachusetts, has still not confirmed the exact cause of death for 22-year-old Saoirse Kennedy Hill, who was found dead at her family’s Hyannis estate this summer.

According to the New York Post, the Office of the Chief Medical Examiner said on Tuesday that the toxicology report was still pending, presumably due to longstanding backlogs that have resulted in delays for up to a year, according to a February Boston 25 News report.

Preliminary autopsy results showed no sign of trauma, and the 22-year-old Boston College student is believed to have accidentally overdosed on an unknown substance or substances. As CrimeOnline previously reported, a source close to the family said that Saoirse was not much of a partier and did not appear to have any issues with drug or alcohol abuse.

But in a eulogy given by her uncle Robert F. Kennedy, Jr., which he posted on Medium, Saoirse had just finished a paper for Boston College and said she was intending and “all-night celebration.” Her uncle said that Saoirse stayed out until 2 a.m. with a close friend, and they stayed up until sunrise at the compound, having gone swimming. Hours after she went to bed, she was found unresponsive.

The Kennedy family did not immediately return the New York Post’s request for comment. It is not clear when the medical examiner’s office expects the toxicology report to be completed.
