Rosario Dawson found her little cousin unconscious last week & she has since passed away.
Law enforcement sources tell TMZ Rosario walked downstairs in her Venice home last Thursday and found 26-year-old Vanez Ines Vasquez lying unresponsive. Paramedics rushed to the scene and transported Vanez, but ultimately they could not resuscitate her.
TMZ was told Vanez -- who worked for Rosario -- had recently been suffering migraines and also had hypertension. TMZ was told early autopsy results point to her dying from natural causes.
Toxicology results are still pending, but TMZ's sources tell them Vanez had no history of substance abuse.
TMZ reached out to Rosario and the family of Vasquez who did not wish to release a statement at this time.
