Metro officials said Davis remained in jail Friday awaiting a bail hearing. Metro spokesman Dan Stessel said that the stolen equipment was worth about $18,200. The defibrillators were stolen from the Greenbelt rail yard and from rail stations along the Green Line, Stessel said. The investigation is continuing, officials said. Stessel said Davis was suspended from his job without pay, per Metro policy. "We will pursue all administrative action up to and including termination," Stessel said.
