A jet-setting band of alleged diamond thieves accused of striking jewelry stores from Portland to Vero Beach, Fla. – once using a Chihuahua as a diversion, another time making a getaway on Jet Skis – appears to be throwing in the towel.

A jury trial set for July 14 in Portland's U.S. District Court appears to be on hold as some members of the gang have pleaded guilty and others have scheduled hearings to do the same.

From late 2009 to the middle of 2011, eight thieves knocked off high-value diamonds from 23 jewelry stores, a cinema-worthy run by pros who sometimes resembled "Ocean's Eleven," other times the Keystone Kops, according to court papers.

Their take in their grab-and-dash thefts was more than $3 million worth of diamonds and jewelry, which they fenced through a Philadelphia company, government prosecutors allege. They struck in Florida, Mississippi, Texas, Tennessee, Nevada, California and Oregon.
