An attorney for a Washington woman charged in connection with a hit-and-run accident that killed two highway workers and injured a third said his client may not be responsible for the accident.

Ramona Morgan’s attorney, Billy Rork, told a Douglas County district judge Thursday that “extenuating facts” need to be presented in the case. Rork made the argument while asking to reduce Morgan’s bond.

Rork also said blood tests show that Morgan had no alcohol or drugs in her system at the time of the Sept. 11, 2007, accident that killed two workers in a construction zone on U.S. Highway 59.

Morgan is willing to be placed on electronic monitoring if she was released from jail while awaiting trial.

Judge Paula Martin denied the request, instead saying she wanted to hear evidence in the case before making any modifications to Morgan’s bond.

A preliminary hearing is scheduled for June 2.
