Ketamine Queen sentenced for Perry's death

The sentencing brings a close to a high-profile investigation that exposed a network of drug suppliers targeting vulnerable celebrities.

Prosecutors described Sangha as a major distributor who ran a 'stash house' in Los Angeles.

Perry's family expressed relief at the verdict, noting that it sends a strong message to those who profit from addiction.

The case has also led to calls for more stringent regulation of ketamine, which has seen a surge in off-label use in recent years.
