A woman from Hollywood and man from Koreatown are facing felony charges alleging they operated a large-scale drug dealing operation that distributed cocaine, ecstasy, oxycodone and other dangerous drugs to customers throughout the Los Angeles area, including a Beverly Hills man who overdosed and died after ingesting pills laced with fentanyl in November 2020.

Mucktarr Kather Sei, 36, of Koreatown, was charged in a federal grand jury indictment released on Feb. 24 that alleges he delivered fentanyl-laced oxycodone pills that led to the death of Beverly Hills resident Ray Mascolo. Mirela Todorova, also known as Mimi, 33, of Hollywood, allegedly orchestrated the drug-delivery service. She was charged last year for possession with intent to distribute cocaine and MDMA,  and is currently being held without bond. Sei is also being held pending an arraignment on March 4.

The indictment released on Feb. 24 charges Todorova and Sei with one count of conspiracy to distribute and possess with intent to distribute controlled substances resulting in death, and one count of distribution of fentanyl resulting in death. The four-count superseding indictment also charges Todorova with the two previously alleged drug counts stemming from the seizure of cocaine and MDMA at her apartment in 2021.

According to the indictment, Todorova provided cellphones and narcotics to Sei and other drivers to deliver to customers. On Nov. 15-16, 2020, after Mascolo allegedly texted orders for oxycodone pills to Todorova, Sei allegedly delivered pills laced with fentanyl that caused Mascolo’s fatal overdose, authorities allege.

Before and after the fatal overdose, other drug customers raised concerns about the authenticity of the pills that Todorova and Sei allegedly distributed, according to the indictment. Prior to Mascolo’s death, another customer texted Todorova, “Yo mimi the oxys are dirty,” complaining that oxycodone pills that were purchased were laced with fentanyl, according to the indictment.

The charges carry a sentence of 20 years to life in federal prison. Anyone with further information is urged to call the DEA at (213)621-6700, or visit dea.gov/submit-tip.
