Michael Jackson reportedly suffered slowed breathing, a symptom of overdose, in the moments leading up to his death.
Misuse certainly includes “overdose,” which seems to be the cause of the star, Michael Jackson.

... which seems to be the cause of his death.
a symptom of overdose是slowed breathing的「同位語」
which seems to be the cause of his death是overdose的非限定性質的「修飾語」（形容詞子句）。
前一句是simple sentence（主要動詞是suffered），後一句是complex sentence（主要子句＋附屬子句）。
leading up to his death是修飾moments的「分詞片語」
