A Prince George's County prosecutor told a Circuit Court jury yesterday that John B. Sydnor raped and sodomized a woman in a church parking lot in Camp Springs last November, then ran over her "three or four times" with her own car.

Sydnor, 21, of Hollywood, Md., is charged with first degree murder, rape, robbery auto theft and several other sex offenses in connection with the death of Kathleen Marie Sebastian 24, of 2714 30th St. SE.

Sebastian's partly nude body was found about 7:30 a.m. last Nov. 6 by a caretaker in the parking lot of the Evangel Assembly of God Church, 6601 Old Branch Ave., Camp Springs, according to the prosecutor, Assistant State's Attorney Leonard L. Casalino.

In the first day of testimony yesterday, two persons testified they say Sydnor with Sebastian in Gus & John's Italian Villa Restaurant on Old Branch Avenue on the night of Nov. 5.

One of the witnesses was Joy Ann Deaton, a friend with whom Sydnor was living at the time. She testified she asked Sydnor to move out of her District Heigths apartment two days after she saw him with Sebastian in the restaurant. On Nov. 30, she said, she found in her living room closet the clothes Sydnor had been wearing at the restaurant the night of Nov. 5. They were spotted with blood, she testified, and she turned them over to polilce.

Casalino told the jury that Sebastian's car was found by police parked at the apartment complex where Deaton lived and that fingerprints on its rear view mirror led police to suspect Sydnor.

In other testimony, Mary Coyle, who lives next to the Assembly of God Church parking lot, said she awoke about 3:15 on the morning of Nov. 6 and heard a man screaming. She said she looked out her window and saw a light colored car moving back and forth about four times then speed off.

Dr. Thomas Smith, assistant Maryland medical examiner, testified that Sebastian, who worked as a cashier for the Memco Department Store in Clinton, died of multiple injuries that included a broken neck and ribs.

The trial is scheduled to continue today.
