“At the high levels of ketamine found in his postmortem blood specimens, the main lethal effects would be from both cardiovascular overstimulation and respiratory depression,” the report reads.

The autopsy also listed drowning, coronary artery disease and buprenorphine (used to treat opioid addiction) effects as contributing factors to his death., which was ruled as an accident with no foul play suspected.

But now, the LAPD and DEA are investigating how the actor had so much of the drug in his system and possession in general.

Matthew had been undergoing ketamine infusion therapy for helping with depression, anxiety, PTSD, drug and alcohol problems, chronic pain and more. His last session had been a week and a half before he died.

“The ketamine in his system at death could not be from that infusion therapy since ketamine’s half-life is three to four hours or less,” the autopsy concluded.

Here are the details about his will, and what happened to his belongings.
