Sheriff Andrew Winston viewed the numbers with dismay. Just Friday, the state Corrections Department had removed a number of felons to state prisons after months of badgering to ease overcrowding in the jail.

"We just got a breather," he said, but with the new wave of arrests from last night's concert, crowding was again the order of the day.

The jail gained at least 30 and possibly as many as 50 people who were unable to make bail and must await trial in a cell, he said.

The large number of arrests led to a special session of General District Court yesterday and judges Jose Davila and Ralph Robertson planned to sit this morning to assign lawyers to those arrested last night.

The arrests also proved troublesome for fans, many of whom will remain in jail in Richmond after the rock group departs.

One of those arrested was Elizabeth Winger, who came with a group from Springfield with tickets to one of the Grateful Dead concerts.

But she spent more time learning about the inside of the city lockup than she did listening to music. A police officer accused her and others of using marijuana in a parked car.
