SKOWHEGAN — A judge ordered a Garland woman accused of killing her 78-year-old sister to be held without bail following a hearing Thursday in which her attorneys attempted to poke holes in the state police’s investigation into the death. Coombs is charged with intentional or knowing murder for the shooting death of her sister, Velma Withee, in Hartland in April; she pleaded not guilty in August. Two days later, the Office of Chief Medical Examiner ruled Withee’s death a homicide and determined the cause to be multiple gunshot wounds to her head. And they withheld the cause of Withee’s death until announcing Coombs’ arrest in June. Related Garland woman arrested in connection with April killing in HartlandPolice had other reasons to suspect Coombs, based on their interviews with her and what she told others about Withee’s death.
