Jury quickly convicts man in 12-hour rape, assault

March 19, 2015 ­– Cobb County District Attorney Vic Reynolds announces that a Marietta man has been convicted of rape and other charges related to a prolonged attack against a woman he had dated.

A Cobb jury on Thursday took about an hour to convict David Martin, 55, of all charges, including rape, aggravated sodomy, false imprisonment, aggravated assault and possession of a firearm during commission of a felony.



About 11 a.m. on Oct. 15, 2013, the victim went to Mr. Martin’s Timberly Drive home to visit. Later, after an argument, he refused to let her leave. Over the next 12 hours, the defendant dragged the victim by the hair, bound her wrists and ankles with zip ties, tied a rope around her neck, threatened her with a handgun and forced her to have sex with him, and also shaved her head. When he finally let her go, he put her cut hair in a bag and gave it to her as a souvenir.

She fled “with her head shaved, her dignity taken from her, her body violated in the worst way,” said ADA Chuck Boring, who prosecuted the case with ADA Courtney Veal. “She had been tied up like an animal -- and treated worse.”

Mr. Martin later wrote to the victim from jail, asking her forgiveness.

Before imposing sentence, Cobb Superior Court Judge Reuben M. Green said, “This was one of the worst rape cases I’ve heard.”

“Over the course of those 12 hours, you tortured another human being,” Judge Green said. “I hear a lot of ugly things and I cannot think of much worse.”

Judge Green then sentenced Mr. Martin to life in prison, plus the mandatory five years on the firearms charge.

Marietta lawyer Charles Engelberger III represented the defendant, who has been in custody since shortly after the attack.

Cobb Police investigated this case. The trial began Monday with jury selection.
