Those details and others are included in the more than 2,100 pages of documents released today by the State Attorney's Office in the criminal case against Casey Anthony -- the 23-year-old accused of killing her daughter last year.
The report from the FBI's lab shows the Cool Blue-flavored Gatorade drink contained an "unknown liquid." The bottle also contained a plastic bag labeled "Disposable Syringe Kit" with a plastic syringe inside of the bag.
A report generated in June and labeled "Summary of results" by Dr. Michael Rickenbach of the FBI indicates chemical tests show the syringe contained chloroform, testosterone, ethanol and water.
Chloroform has been depicted in movies and on television when a person uses a rag soaked in the liquid to cover the mouth and nose of another, making the victim lose consciousness. A person can die if too much of the chemical is inhaled. Chloroform also is the byproduct of contact between chorine used in swimming pools and skin, sweat or urine. Commercially, it is used in refrigeration.
Testosterone is a natural occuring hormone in men and women. Levels decline gradually with age and the hormone can be prescribed as a controlled steroid to prevent or reduce osteoporosis, diabetes, cardiovascular disease and other diseases and disorders.
Investigative reports released last year show that someone at the Anthony home used the family computer to search the Internet for directions on how to make chloroform and ' neck-breaking.' Investigators also found traces of chloroform in the trunk of Casey Anthony's car, earlier reports show.
The FBI reports released today also show a doll recovered from Casey Anthony's white 1998 Pontiac Sunfire GT had "faint yellowish stains" on the front and back of its white clothing. The June lab tests showed slight traces of chloroform residue on the doll, according to Rickenbach.
But a later test in July indicated no chloroform on the doll. Other reports show the yellow stains may have been urine.
The documents show photographs of the doll, Gatorade bottle and syringe found at the scene.
Also included in the latest reports are communications between FBI lab technicians and sheriff's office investigators.
Authorities ruled her death a homicide but could not determine how she died.
The state is seeking the death penalty against Anthony, who remains in the Orange County Jail.
So far, more than 10,000 pages of documents have been made public.
