Mr. Kelly stayed in jail in Camden until Ms. Kosmin raised enough cash to post his bail, the Camden County Prosecutor, Edward F. Borden Jr., said today. Early Monday a friend of Ms. Kosmin, Tammy Ann Molewicz, 25, also of Medford, posted the $1,000 cash and picked Mr. Kelly up in her red Corvette, Mr. Borden said.

The three drove to Medford, where they stopped at a convenience store to buy food for Mr. Kelly, Mr. Borden said. When Mr. Kelly and Ms. Kosmin returned, the prosecutor said, Ms. Kosmin walked up to the open car window and shot him.

"It was a premeditated, planned and carefully executed murder," Mr. Borden said. "She wanted to get back at him for his beatings and then see that he didn't do it again. She had had enough."

Ms. Kosmin and Ms. Molewicz were arrested on Tuesday and charged with first-degree murder. They are being held on $200,000 cash bail each. Unfair, Women's Group Says

The body, with two bullet wounds in the head, was found by hunters later on Monday in Wharton State Forest in Waterford Township, face down in a cranberry bog; his head was covered with a pillowcase, the prosecutor said. The body was wrapped in a sheet and twine was tied around the neck, legs and hands. Authorities also found a .32-caliber revolver at the scene, he said.
