What types of evidence are commonly used in sex crime prosecutions?

Answer:
The most common evidence is testimonial — the accusations and statements made by another person against the accused, sometimes gathered through a police interview, or, particularly with children, through a more controlled forensic interview. This testimony often becomes the most heavily relied-upon evidence in the case. Other evidence can include DNA, school records, and counseling records — anything documenting behavior that a prosecutor might argue was caused by trauma from the alleged offense. If you’re under investigation for a sex crime and are concerned about the evidence being gathered against you, give us a call so we can begin helping you.

Testimonial Evidence Is Usually the Core of the Case

Because Georgia law allows a single witness’s testimony to support a conviction on its own, the accuser’s account is almost always the centerpiece of a sex crime prosecution. Everything else the state gathers tends to function as support for that testimony rather than a substitute for it.

Forensic Interviews With Child Witnesses

When the alleged victim is a child, statements are often gathered through a forensic interview conducted by a specially trained interviewer, typically at a child advocacy center, rather than a standard police interview. These interviews are designed to reduce trauma and follow a structured, non-leading format, but the technique used still matters — how questions are asked can meaningfully affect what a child says and how reliable that account turns out to be.

The Child Hearsay Exception That Makes This Possible

Normally, a statement made outside of court can’t be repeated in court by someone else. Georgia carves out a specific exception for this situation: under O.C.G.A. § 24-8-820, a statement by a child under 16 describing sexual contact or physical abuse can be admitted through the testimony of the person the child told — a forensic interviewer, a parent, a doctor — as long as the state gives advance notice and the child is available to testify or that requirement is properly waived.

DNA and Physical Evidence

DNA evidence, when it exists, can establish contact occurred, but it rarely settles the central dispute in these cases on its own. It doesn’t establish consent, the specific act alleged, or when the contact happened relative to the timeline described — those questions usually still come down to the testimony surrounding the physical evidence.

School and Counseling Records as “Trauma Evidence”

Prosecutors sometimes introduce school records, counseling notes, or other documentation showing behavioral changes — declining grades, new anxiety, withdrawal from friends — and argue that pattern is consistent with trauma from the alleged abuse. This kind of evidence requires real context, since many things unrelated to the accusation can produce the exact same behavioral changes, and that’s often a genuine point of challenge.

5 Star Rating

Brett and his team were beyond supportive, helpful, gracious, caring and knowledgeable! We went through the most challenging and difficult time in our life and he was there every step of the way. With results we could never have imagined but definitely prayed for.

Not to mention his level of professionalism. From the first time we spoke to the first time we saw him in court. He stood out from almost every other attorney there. We were so appreciative that our attorney looked and was so professional, pulled together and prepared. When so many others were none of these things.

Thank you just doesn’t seem like enough to convey our feelings and appreciation.

I tried to write this several times and it brought me to tears. First may I say this has been the hardest three years of my life. Five lawyers I interviewed and none even understood the law as it applied to my case. So I thought I would try one more and it was Brett. From our first conversation together I knew he understood the law and was the perfect one for the case. I want to say how he prepared the case and presented it, achieving a full dismissal and ruling the police violated my first amendment rights. Complete genius!!!!

If you're reading this review and unsure, stop...call Brett. He always returned my call or texts within a couple hours, never more than 24 hours. He was always courteous and knowledgeable, trust me he talked me off the ledge a couple times. I would have given him 10 stars but 5 was the only option. Thank you Brett for all you did for me!!!!!
