The official cause of death for Ace Frehley, the guitarist who was a founding member of hard-rock band Kiss, has been released, confirming details his family shared in October.

The medical examiner for New Jersey’s Morris County said in a report, published by TMZ, that Frehley died of “blunt trauma injuries” to his head suffered during a fall. His death was ruled an accident. The report listed injuries including a brain bleed and fractures to his skull.

Frehley’s death Oct. 16 was announced by his family, which said he had recently suffered a fall. “In his last moments, we were fortunate enough to have been able to surround him with loving, caring, peaceful words, thoughts, prayers and intentions as he left this earth,” the family said in a statement at the time. Frehley was 74.

“We cherish all of his finest memories, his laughter, and celebrate his strengths and kindness that he bestowed upon others,” the statement continued. “The magnitude of his passing is of epic proportions, and beyond comprehension.”

Frehley, known also for his Spaceman alter ego, died less than two weeks after canceling the remainder of his 2025 live performances due to undisclosed “onging medical issues.” He was also hospitalized in late September after suffering a “minor fall” in his studio, his tour manager John Ostrosky announced. Though the rocker was “fine,” doctors urged him to take time from the road to recover, prompting him to cancel his appearance at the Antelope Valley Fair in California.

The musician was among the original members of Kiss, playing with the band for about a decade, from 1973 — when he formed the group in New York with Paul Stanley, Gene Simmons and Peter Criss — until 1982, when he quit not long after Criss left.

The band, which had its final show in 2023, was known for flamboyant performances, and costumes and heavy makeup. Despite his relatively short tenure, Frehley proved instrumental in creating the band’s stomping and glittery sound, as heard in songs like “Detroit Rock City,” “Rock and Roll All Nite,” “Strutter” and “I Was Made for Lovin’ You.” He was part of a reunion tour with the band from 1996 to 2002.

“He was an essential and irreplaceable rock soldier during some of the most formative foundational chapters of the band and its history,” the band said of Frehley following news of his death. “He is and will always be a part of KISS’s legacy. Our thoughts are with Jeanette, Monique and all those who loved him, including our fans around the world.”

The 2014 Rock and Roll Hall of Fame inductee is survived by his wife, Jeanette; his daughter, Monique; his brother, Charles; his sister, Nancy; and several nieces and nephews.
