Actress Naya Rivera's toxicology report has been released and according to the report, a combination of prescription drugs and alcohol were in her system when she drowned.
According to a medical examiner's report, the actress drowned while on Lake Piru with her son.
The report obtained by ABC News found therapeutic levels of phentermine, low levels of amphetamine and diazepam, caffeine, and a blood-alcohol level of .016%.
Investigators found three 12-ounce cans of White Claw hard seltzer on Rivera's boat.
One was empty, another was about three-quarters full and the third was unopened.
Investigators say the boy told them they both jumped into the water, counting down 1,2,3.
She then pushed him back into the boat, and then at one point put her arm into the air and yelled "help."
She then disappeared into the water.
Workers at the lake later found the boat with just her son on board, asleep.
Rivera's mother Maya told investigators that Naya had vertigo that got worse in water.
Her death has been ruled an accidental drowning.
