Texas Police Pursuit - Terry Sillers [ Aryan Brotherhood General] Harley Davidson Motorcycle Chase

In an extraordinary turn within a murderous prison gang where betrayal means death, an Aryan Brotherhood of Texas general has been secreted away under federal protection after agreeing to testify against dozens of fellow gangsters charged in Houston with racketeering, murder and other offenses.

The last time the world saw Terry Sillers was in 2011 as he flew along a Fort Worth area roadway on a Harley Davidson motorcycle, leading police on a wild chase captured by a television news helicopter.

His no-turning-back decision to cooperate with the government was made public recently in a rare disclosure in court papers.

"We are very confident he is in a very safe position," federal prosecutor Jay Hileman said Wednesday. "We can't comment on the extent of his protection."

Sillers, 49, pleaded guilty to racketeering earlier this year just before 34 other gang members and associates were indicted.
