Actress Daveigh Chase was discovered in the back seat of a vehicle near a meth pipe on June 4, almost two weeks before her tragic death.

Per the Los Angeles Medical Examiner’s report obtained by Page Six Tuesday, the “Lilo & Stitch” actress — who died June 16 at the age of 35 in Los Angeles — had complaints of “headache, weakness, confusion” and “right thumb pain” before 911 was called by an unnamed bystander.

The “Donnie Darko” actress was transported by paramedics to a local hospital, where she was diagnosed with multiple infections and “advanced and untreated HIV/AIDS.”

She was also found to have suffered from a right thumb infection, and had been engaging in drug use, per the report.

Toxicology screenings showed methamphetamine and fentanyl in Chase’s system, as well. Despite hospitalization, the “Ring” star’s “health declined until” her death in June, the report stated.

Chase’s cause of death was previously revealed to be acquired immunodeficiency syndrome, with chronic polysubstance use also listed as a contributing factor.

Following news of her death, Chase was seen in video footage obtained by The Post looking weak and dramatically thin on the floor of a trailer or tent while staying on Skid Row — despite the fact that she was said to have had $400,000 in personal property.

Prior to her death, the former child star’s alleged boyfriend, Roy Hernandez, had set up a GoFundMe campaign in an effort to help her “find comfort and peace” as she faced her final days. Hernandez called Chase “a light in my life” in the fundraiser’s description.

“Many people know her as a talented childhood actor from ‘Lilo & Stitch,’ ‘Spirited Away,’ and ‘Donnie Darko,’” he wrote at the time. However, he added, “Behind the scenes, she’s faced more than her share of hardship,” citing “a difficult childhood and a painful falling out with her family.”

Hernandez claimed the late actress had been “bullied” and “struggled to find safety and happiness in downtown LA,” and noted that they “found moments of happiness and hope” together.

John Ryan, Chase’s longtime manager, pushed back and discouraged fans from contributing to the GoFundMe, telling The Post that “none of us friends or her family” had heard of the “man claiming to be her ‘boyfriend.’”

“I can confirm Daveigh has a trust account set up at SAG to cover all costs,” Ryan said in June, claiming she had “millions” in unclaimed residuals when she passed.

He also said he and the actress’s stepsister, Gaia Brown, had attempted to locate and help her with the aid of a private investigator last year — but she “disappeared” after they were able to speak to her on the phone.

Ryan called Chase “the sweetest and brightest light in Hollywood” while lamenting her death.
