Luke Perry "never regained consciousness" following his stroke last week.
The 'Beverly Hills, 90210' star passed away on Monday at the age of 52 after he was admitted to hospital last week when he suffered a stroke, and while his condition at the time of the stroke was unknown, sources have now said he never woke up from the "heavy sedation" he was put under by ambulance staff.
An insider told People magazine: "He never regained consciousness. Things were so dire that they put him under heavy sedation. He was gone, basically, by the time he got to the hospital."
News of Luke's passing was confirmed by his representative on Monday.
