Rachel Shannon

suddenly died in their home.

Shortly after, police responded to the scene where they found 39-year-old Sarah dead in the home that she shared with Robert.

According to what police have stated in their reports, Sarah was alone in the hours leading to her death

and there were no obvious signs of trauma when they first examined her.

After finding her body, she was sent off to the medical examiner for an autopsy where they found that she had died of an overdose caused by a cocktail of different drugs in her system.

The ME listed her death as oxycodone, gabapentin, and diphenhydramine, or better known as Benadryl intoxication.

So, she died from intoxication from all of those drugs being in her system.

Her manner of death is currently listed as undetermined.

Of course, after her death was announced, her family was devastated.

Not only that, but those who supported Grace were also devastated.

The family's lawyer released a statement saying that the family is deeply saddened by the death of another young woman involved in Robert's life, and they hope that unlike Grace's case, the police in the area do an actual investigation.

However, after Sarah's death, her family did announce that she actually has two different life-threatening diseases, which may have actually contributed to her death.

Like I said, she was diagnosed with Perth's disease as a child, but she also had been diagnosed with mass cell activation syndrome as an adult.

Now, mast cells are blood cells in your body's immune system that help you fight infection, but they are also involved in allergic reaction.

In someone with MCAS, their mast cells release an inappropriate amount of chemicals such as histamine into the body, causing allergy-like symptoms among a wide array of other symptoms.

So, someone with MCAS will suffer from repeated episodes of allergic reactions with symptoms such as wheezing, itching, rashes, sweating, headaches, low blood pressure, and fainting.

This condition has no cure,

but it can be treated with various medications.

While MCAS in itself isn't necessarily fatal, it can cause a severe allergic reaction called anaphylaxis, which can be fatal if it isn't treated immediately.

I have also seen a lot of reports where the family's lawyer referred to Sarah's Perth disease as also a fatal condition,
