HAMILTON TOWNSHIP — A gynecologist testified Monday that the teen girl who accuses Roderick Knox of sexually abusing her showed physical signs of assault.

The prosecution rested its case after testimony from Dr. Susan Kaufman, who examined medical reports and photographs of the then-15-year-old girl and said tears in her vaginal wall and redness around her cervix were indications of forcible intercourse.

That testimony conflicted with that of Dr. Paul Allen, who said before Superior Court Judge Bernard DeLury last week that he did not believe inflammation in those same photos indicated any recent traumatic injury.

Knox, a suspended Atlantic City Fire Department captain, and his wife fostered the girl at their Egg Harbor Township home for three weeks in August 2010. The teen said Knox had sex with her several times during that period.

The defense says she fabricated her allegations because she was angry with Knox, 45, because he planned to report to the state that she said she had a sexual attraction to him. The girl’s name is not being published because of the nature of the alleged crimes.

Kaufman, who has a private practice in Cherry Hill, said the tears she saw in the pictures were signs that the girl had sex unwillingly.

She said that in a consensual situation there would not be that degree of tearing because the muscles are relaxed, whereas in a forcible situation the muscles contract and cause more friction.

The defense presented Allen as its expert witness last week. Allen, who has a medical license in Mississippi and a retired license from California, said it could not be fully discerned from the state's medical report whether there was evidence of an acute traumatic injury.

Youma Kabia-Williams, an intake worker with the Division of Child Protection and Permanency, testified that she met with the Knoxes and gave them her contact information but they never mentioned any problems with the girl.

The defense has said that Knox planned to report the girl's alleged attraction but that he was not able to get in touch with someone at DCP&P, formerly known as the Division of Youth and Family Services, or Helping Hands, a subcontractor that facilitates foster homes for the state, before she made her accusations.

Assistant Prosecutor John Flammer questioned Kabia-Williams about what phone numbers she provides and instructions for reaching someone at the department in an emergency. She said Knox could have talked to any supervisor about any issue, even when she was on vacation for some time over that month.

Kabia-Williams also said that the girl had a history of defiance. She was temporarily placed with the Knoxes while the state conducted background checks on relatives in order to find her a permanent home.

The defense planned to continue presenting witnesses today, possibly resting its case as well. Knox said he also planned to testify on his own behalf.
