SLAIN MEDICAL MISSIONARY EULOGIZED AT MEMORIAL SERVICE (Mobile, Alabama-AP) -- Dr. Martha Myers is being remembered as a Christian martyr who spent more than two decades as a "beacon of light" in a "dark land where there is no Gospel witness." The tribute came at a memorial service in Mobile, Alabama, for the medical missionary who was shot to death along with two other Americans at a hospital in Yemen Monday. Several hundred people -- among them Baptist church leaders and former missionaries -- took part in the service, which included hymns, Bible readings and tearful recollections. The man arrested in the killing is described as an Islamic militant. Myers was was buried Tuesday on the hospital grounds in Yemen, where her father said the grave will be "a testimony."
