She died.

The specific circumstances of her death are not known.

The fracture at the base of her skull might reflect the cause of her death, or it might have occurred immediately after as part of the initial stages of her post-mortem treatment.

There is no way, from the available evidence, to determine which.

After her death, the people who knew her performed a complex sequence of actions on her body.

They opened the base of her skull and used a tool to remove the brain.
