The FBI is conducting an investigation into the smuggling of contraband into the Federal Detention Center in Honolulu after two state inmates admitted receiving tobacco and marijuana there, said federal prosecutor Jonathan Loo.

Loo made those statements during the sentencing this morning of Bradley Souza for possessing tobacco and marijuana at the detention facility last December and attempting to possess more tobacco and marijuana in February. Souza was sentenced to 15 months in prison.

Another former state inmate, Dayven Joseph, was sentenced to two years in federal prison last month for possessing and providing the contraband to Souza last December and attempting to possess more tobacco and marijuana in February.

Federal prison officials found the contraband hidden in slippers Joseph was wearing following a family visit in February. The slippers were not of the kind available to inmates at the facility.
