The day Matthew Perry died, in October last year, he himself is said to have ordered his assistant to give him several intravenous doses of ketamine, according to the assistant's own statement, reports The Guardian.
The information suggests that Perry asked the assistant to give him a dose at 8:30 am - and then another four hours later. Only 40 minutes after that, Perry is said to have asked for a larger dose.
After that, the actor is said to have asked the assistant to prepare his pool, whereupon the assistant left the home to run errands, according to the documents.
Large amounts of ketamine in the blood
When the assistant returned, Perry was found dead in the pool.
During the autopsy, the doctors found traces of the drug ketamine in the blood. The levels of the drug measured in Perry's body were equivalent to the amount used to anesthetize a patient during an operation.
The police launched a collaboration with several other authorities, including the drug enforcement agency, in May this year to investigate what led to the 54-year-old star's death. Initially, the case was written off as an accident.
Five suspects
On Thursday, the investigation against five suspects - including the assistant - for Perry's death was presented. According to the authorities, a "large criminal network" that sold ketamine has been discovered, where two doctors are suspected of being driving forces.
The suspects are said to have discussed Perry's death shortly after it occurred and together tried to destroy evidence and conceal their involvement in the events.
They exploited Matthew Perry's addiction problems to make money. They knew they were doing wrong, said prosecutor Martin Estrada during a press conference.
