ANNAPOLIS, JULY 6 -- A 25-year-old Glen Burnie waitress whose husband was gunned down in a parking lot last week has been arrested and charged with murder for allegedly hiring three men to carry out the slaying, Anne Arundel County police said today.

The three suspected of performing the killing also are in custody on murder charges.

Michael K. Boyd, 25, was shot at 10 p.m. Thursday in the parking lot of his apartment building and died at North Arundel Hospital an hour later.

Police spokesman V. Richard Molloy said Jody Boyd, who has three young children, told investigators after her arrest Sunday that her husband "beat her a lot and beat the children."

But Molloy said police have not been able to substantiate that. "She has never called the police on him, there were no bruises on her or the children, and there were no calls made to social services," Molloy said.

Molloy said police suspect that Jody Boyd, who quit her job as a waitress at the Rax Restaurant in Glen Burnie last week, asked two men who worked in a nearby pizza restaurant to kill her husband for an unspecified share of his $27,000 insurance policy. The two men then appear to have enlisted a 15-year-old friend to act as an "adviser," according to Molloy.

Molloy said the men called Jody Boyd at 9 p.m. Thursday and told her to get her husband out of the house. Michael Boyd was dispatched to a nearby Hardee's Restaurant to buy hamburgers, Molloy said, and was shot in the back, face and buttocks when he returned home.

Molloy said Jody Boyd immediately called police and told them she had heard shots, ran outside and found her husband's body in the parking lot. She told police that her husband had received several death threats during the previous week, Molloy said.

He said several of Michael Boyd's friends told investigators they had overheard Jody Boyd talking with the two older men about killing her husband, and didn't take it seriously.

Police said they arrested Michael Gregory Woods, 21, of Pasadena, who they suspect was the gunman, at 1:30 p.m. Saturday. Donald A. Dare, 19, of Glen Burnie, who police believe drove the getaway car, and James Chris Hayes, 15, of Pasadena, were arrested Sunday. All were charged with first-degree murder, as was Jody Boyd.

Molloy said Jody Boyd was arrested at 1 p.m. Sunday when she came to the Glen Burnie police station to claim her car, where dectives had taken it to be dusted for fingerprints. All four were being held without bond today in the County Detention Center.
