The details surrounding Julian Sands' cause of death will remain unknown.
 
Nearly one month after remains belonging to the British actor, 65, were found on Southern California's Mount Baldy, an official for the San Bernardino County Sheriff's Department told E! News that his cause of death has been deemed "undetermined."
 
The public information officer went on to note that the ruling was "due to the condition of the body," adding the outcome is "common when dealing with cases of this type."

Back in January, Sands was reported missing after he set out on a hike on the mountain located about 50 miles east of Los Angeles. At the time, rescuers searched the area both on foot and by helicopter, though their efforts were called off two days after the report due to the avalanche risks and extreme weather conditions. 

Hikers found his body five months later on June 24 in a wilderness area located on the mountain, according to the San Bernardino County Sheriff.

The England native was known for his roles in films such as Warlock, Arachnophobia and A Room with a View and appearances in TV shows including Dexter, 24, Smallville and Rose Red, the 2002 miniseries of which he co-starred alongside Melanie Lynskey. After his passing, the Yellowjackets star paid tribute to her beloved friend.

"You were gracious and patient and tons of fun," she wrote in part in a June 28 Instagram post. "We lost touch, but I have never forgotten your kindness and I will never forget you. My heart goes out to your family and loved ones."

His family, including wife Evgenia Citkowitz and his three adult children, also reflected on the actor's legacy.

"We continue to hold Julian in our hearts," they told The Independent in a June 24 statement, "with bright memories of him as a wonderful father, husband, explorer, lover of the natural world and the arts, and as an original and collaborative performer."
