If a person's life is spent in the spotlight, it is natural that their death will be as well.

In Hollywood, everything is complete with glitz and glamour - however, like in real life, some horrific murders may occur.

There is sure to be some friction and vengeance among these celebrities in a city of high risk and big reward.

When celebrities die, admirers immediately suspect that their deaths were staged or were the result of something more nefarious.

These horror stories appear to be straight out of a murder mystery film. The plot, on the other hand, is true, and the actors are not acting.

Here are some of the most mysteries deaths in Hollywood history.

Bruce Lee

Bruce Lee, a Chinese-American, fell asleep one evening and never awoke.

It seems strange because he was in fantastic shape, making his death difficult to comprehend.

According to sources, he died of cerebral edema, which means his brain expanded due to an excess of fluid. The cause of the edema, on the other hand, remains unknown.

George Reeves

"Superman" George Reeves died of a headshot wound in the 1950s.

The actor's death, at the age of 45, was deemed a suicide. Fans believe he was a murderer or the victim of an accidental shooting because the gunshot wound occurred during a visit with three companions.

Diana, Princess of Wales

Despite the fact that Princess Diana was attempting to live her life as normally as possible following her divorce from Prince Charles, many fans speculated that she had been murdered, most likely by a staged automobile accident.

Her death occurred in the manner she had foreseen, but no one will ever know if the crash was an accident, as investigations stated, or orchestrated, as she had initially suspected.

Heath Ledger

Heath Ledger had just finished filming scenes for "The Dark Knight" as the Joker on the night he died. However, in order to prepare for the role, he reportedly secluded himself in hotel rooms for months and scrawled up a Joker journal that appears to be the work of a serial killer.

His death was ultimately deemed an accident, but fans of the actor haven't stopped wondering if his portrayal of the villain was too harsh for one person to stomach and pushed him over the edge.

Steve Irwin

Steve Irwin, a crocodile hunter, died in 2006 after being attacked by a stingray. However, he was a seasoned specialist in this type of animal encounter, and stingrays are typically not hostile and would never kill.

His death from a stingray barb to the chest was described as a one-in-a-million occurrence.

It was so uncommon that his death is thought to be the only lethal stingray attack captured on camera.

Marilyn Monroe

The death of Marilyn Monroe sparked some media attention. Her death was declared a drug overdose suicide.

Many believe she was going to go public with her affair with JFK at the time, giving someone a reason to silence her.

Natalie Wood

Natalie Wood's glamorous and famous life came to an end when she was discovered dead in the water while boarding her yacht.

Investigators claimed that her drowning was "accidental," but many believe she was murdered by her unstable husband Robert Wagner, as they were frequently embroiled in conflicts and did not have a healthy bond.

Detectives believe Robert threw Natalie into the lake following a quarrel the night she died.

Brittany Murphy

Brittany Murphy, 32, died after experiencing "flu-like symptoms." She allegedly died in her mother's arms after moaning about being unable to breathe.

According to an autopsy, she died of pneumonia, anemia, and various drug intoxication from prescription and over-the-counter drugs.

Fans believe her husband, Simon Monjack, played a role in her death because it was evident what she was being treated for with the medications, but he also reportedly did not want an autopsy performed on her.

Prince

An autopsy determined that Prince died as a result of an accidental overdose of the narcotic fentanyl in an elevator at his Paisley Park mansion.

However, the singer's friends and former wife stated that he did not use narcotics. It is currently being investigated where he obtained the medications and who supplied them to him.

River Phoenix

River Phoenix died at the age of 23 from a combination of heroin and cocaine intoxication.

His acquaintances stated that the actor did not use drugs, while others said that he kept his drug use disguised.

His fiancée Samantha Manthis, on the other hand, said that she suspected something was wrong that night after witnessing a friend hand River a Dixie cup of liquid and instruct him to drink it so he would feel "amazing."

River Phoenix was dead 45 minutes later.
