A 36-year-old Seat Pleasant woman died yesterday at the Washington Hospital Center of wounds suffered Saturday night when she was shot by a District police officer after allegedly firing a weapon at him, police reported.

Police said Jeanette G. Boykin, of 4606 Nash St., was wounded by the officer in a vacant lot at the rear of the 3000 block of 14th Street NW about 7 p.m. Saturday when he was shot at while investigating a report of an assault in progress. The officer, Manuel Rivera, was not hurt, police said.

They said a woman had been firing a gun at a man in the lot, apparently in the course of a domestic dispute, when Rivera approached and ordered her to drop the weapon.

The woman then fired two shots at Rivera, who returned the fire, shooting once and wounding her in the lower abdomen, police said.

Boykin was taken to the Medstar unit of the Washington Hospital Center, where immediately after the incident she was reportedly alert and talking, police said. At the hospital, they said, she was charged with assault with a dangerous weapon.

Police said Boykin's condition deteriorated rapidly and she was rushed to surgery.

A hospital official said the woman was in "grave" condition in the hospital's intensive care unit throughout the night and died at 4 p.m. yesterday.

Boykin's body was taken to the D.C. medical examiner's office for an autopsy, police said.

They said Rivera, an officer with four years' experience who was assigned to the 4th District, was placed on routine administrative leave pending an investigation of the incident.
