The FBI, Honolulu police, Homeland Security Investigations and California Drug Enforcement Agency uncovered a methamphetamine trafficking operation out of Makiki apartments that distributed nearly pure meth from a source in Vallejo, Calif.

The U.S. Attorney’s Office on Friday charged Samoa Lefiti, Larry Sylva, Natasha Hoover-Crawford, Stacy Stender and Carl Kazanowski in a criminal complaint with conspiring to distribute 50 grams or more of methamphetamine between October 2013 and March 4.

The complaint says the Honolulu Police Department began receiving numerous complaints in October 2013 about drug activity in the Cartwright Neighborhood Park area. HPD found the source of the drugs appeared to be a Kinau Street apartment, where  Hoover-Crawford lived.

The complaint said meth from seizures from vehicles and shipments connected to the operation tested 97 to 100 percent pure.
