A 31-year-old Arlington man was arrested early yesterday morning and charges in the death of a 22-year-old Arlington woman found shot to death Friday night, police reported.

Police said that Ronnie James, of 6321 N. 19th St., was charged with murder in the fatal shooting of Donna Marie DePugh of 838 S. Frederick St. Her body was discovered by police outside her apartment shortly after 9:30 p.m. Friday after neighbors reported hearing gunshots.

Described by police as an acquaintance of DePugh, James was arrested shortly before 1:30 yesterday after he turned himself in at the police station. He is being held without bond at the county jail pending arraignment Monday, police said.

In 1977, James was a key prosecution witness in the murder trial of Richard Lee Earman. A former cellmate of Earman, James testified that Earman confessed that he killed real estate agent Alan Foreman and his fiance Donna Shoemaker. A jury acquitted Earman of murder charges.

Earman, currently in jail awaiting sentencing on a murder conspiracy charge, recently testified that he killed the couple at the request of a former life insurance salesman.

Jail authoriites said yesterday that Earman, who can never be retried on murder charges, was not being held in the same cell as James.
