Brooke Mueller, a Palm Beach socialite and actress, has been revealed as the unnamed celebrity questioned by police in connection to Matthew Perry's death. Perry's passing, due to the effects of ketamine, led to a widespread investigation involving the LAPD, DEA, and postal inspectors to find his supplier. Mueller, who met Perry during his time in rehab, has been contacted multiple times and had her California home searched by authorities. Despite being cooperative and hiring lawyers, Mueller's past choices have put her in a position to provide information in the case. As the inquiry comes to a close, multiple individuals may face charges in the investigation. With ties to both Perry and Charlie Sheen, Mueller's involvement sheds light on the complex world of celebrity relationships and the impact of substance abuse.
