Rosario Dawson's cousin, who the actress found unresponsive in her L.A. home last week, has died.

TMZ reported that Dawson discovered her cousin, Vanez Ines Vasquez, unconscious in her home last Thursday and called paramedics right away, but when they got there they were unable to resuscitate the 26-year-old.

The New York Daily News noted that Vasquez was then transported to a local hospital where she was pronounced dead.

Sources told TMZ that Dawson's cousin has been dealing with migraines and had hypertension. An autopsy will be performed to determine the exact cause of her death. In addition, toxicology results are pending and will determine if Vasquez had anything in her system when she died.

Neither Dawson or anyone in the star's family has commented on the death at this time.
