CLEVELAND, Ohio -- A 20-year-old woman pleaded guilty Monday to involuntary manslaughter for her role in the March death of her friend outside of the International House of Pancakes in Cleveland Heights.

Rachella Womack is set for sentencing in next month and has agreed to testify against Sharon Moore, 24, also charged in the case, her attorney James A. Jenkins said.

Womack was one of three women asked to leave the restaurant, in Severance Town Center, after a security guard confronted the women who were cussing loudly and causing a disturbance in a bathroom, according to court records.

After a second disturbance with patrons at another table, the women were asked to leave. As the guard escorted the group out, the confrontation got physical -- with the women jumping and kicking the guard. Witnesses said one of the women yelled about getting or grabbing the guard's gun. His gun fired, striking 25-year-old Nadia Williams in the head, according to police.

Moore and Womack were indicted in April on charges including involuntary manslaughter, assault, abduction, inducing panic, disorderly conduct, aggravated trespass and inciting violence. A third woman was initially charged but those indictments were later dismissed.

Moore's case is still set for trial this week in Cuyahoga County Common Pleas Judge Michael Astrab's courtroom, and a video that captured the incident could be presented as evidence in the case.
