A 38-year-old man has been sentenced to four years and nine months in federal prison for manufacturing methamphetamine at his Waikiki apartment.

U.S. District Judge Michael Seabright on Thursday sentenced Allen Hanaoka, who was arrested in May last year after federal Drug Enforcement Administration agents and Honolulu police officers found a small-scale meth-producing operation and trace amounts of meth at the apartment.

Hanaoka pleaded guilty.

Seabright earlier this month sentenced Hanaoka's codefendant Cindy Shishido, 36, to four years in prison for distributing methamphetamine.

The two lived at the apartment along with Shishido's 6-year-old son, federal prosecutors said.

In sentencing Hanaoka and Shishido, the judge underscored the risk of harm to the boy and others at the high-rise apartment building as a result of the methamphetamine manufacturing operation, the U.S. Attorney's Office said.

"This case shows that people who are involved in meth lab operations will do so without due regard to the safety of families or even our young children who are exposed to these deadly fumes and toxic meth residue," U.S. Attorney Ed Kubo said.

"As a result, we must sentence these individuals harshly because of the extreme dangers they pose to innocent and helpless victims."
