When Mack W. Cantrell's coffin was opened yesterday in the Bible Way Church on New Jersey Avenue NW women in black veils let out sorrowed wails and their arms flew into all reaching toward the coffin.

An usher handed out tissue paper and watched over Cantrell's relative as mourners passed by his coffin, and a church sister sang "Amazing Grace." As one man approached the coffin he did a quick step, fell to one knee and made the sign of the cross then stood and reached in the coffin to touch Cantrell's hand.

Cantrell's body was dressed in the blue uniform of the D.C. Department of General Services Building Security. He was shot while wearing the uniform on March 9 during the Hana take-over of the District Building where he had been a security guard.

Cantrell died July 4 of a heart attack, according to the D.C. Medical Examiner, after recovering from the gunshot wound to his head that he received during the early hours of the Hanafi take-over.

"I don't know what the coroner the medical examiner would say," said Bishop Smallwood E. Williams of Bible Way, "but I believe that most of us believe that the cause of the [WORD ILLEGIBLE] timely passing of our brother was a result of the outrageous, brutal act and violence which shocked this city March 9."
