The sentencing of a cross-country drug syndicate boss has been delayed. Dallas Oran Edward Shave, 37, pleaded guilty to a representative charge of supplying meth, three counts of possessing an illegal firearm, and conspiring to sell meth in December. Shave was one of seven people arrested after Operation Book, a police investigation into the meth ring. Police calculated the group sold more than 600 grams of meth in Marlborough between September 2015 and February 2016, with an estimated street value of up to $739,000. Shave was supposed to be sentenced on February 15, but the case was adjourned to the Blenheim District Court on April 24. A Blenheim woman and an Auckland woman also charged during Operation Book have entered not guilty pleas and will appear on Tuesday for a pre-trial callover.
