Dr. Martha Myers was well known for her trips over rugged roads of the countryside to treat the illnesses and wounds of some of the poorest people in Yemen. In December 2002, an Islamic militant entered Jibla Baptist Hospital, where Myers worked, and killed three IMB medical missionaries: Myers, hospital director Bill Koehn, and purchasing agent Kathy Gariety. Donald Caswell, a pharmacist, was wounded but survived the attack.
