Why Would Police Inactivate A Sexual-assault Investigation Because The Suspect Won’t Respond To An Interview?

Location: Georgia, United States

Hi guys! This is a throwaway account for privacy reasons!

I reported a sexual assault to police in GA and I’m trying to understand what’s happening procedurally. I’m not asking anyone to determine whether the person is guilty.

I gave police a sworn statement and a collection of text messages between me and the person I reported. I also provided photos documenting the alcohol involved and videos from that night from while I was blacked out.

There were no eyewitnesses to what happened in the room. The detective interviewed his roommates, but they said they weren’t aware of anything relevant.

What confuses me is that the person I reported made statements to me afterward that seem significant. The morning after the incident, I texted him that I had blacked out and asked what happened. I didn’t receive a response to that specifically until I asked about it months after in later conversations. He acknowledged that I had blacked out and described sexual activity occurring that night.

When I specifically asked whether I had actually had sex with him rather than merely tried to initiate it, he responded that “it slipped in,”while maintaining that we didn’t “fully” have sex in an attempt to downplay it.

He later described me as really drunk and gave his version of why he took me home. I subsequently confronted him about sexual activity occurring while I was incapacitated, which he disputed but kept giving me an inconsistent changing story. All of these conversations were over text and had been submitted as evidence to the detective, including what was essentially his admission.

As of now, the detective has repeatedly attempted to interview him, but he hasn’t responded. I was recently told that she would make one final attempt to contact him and that, if she couldn’t reach him, the case might be inactivated unless additional evidence became available.

This is what I don’t understand: why would his refusal/failure to speak with police cause the investigation to become inactive when police already have my sworn statement, contemporaneous and subsequent text messages, his statements acknowledging sexual contact, and photo/video evidence of my intoxication? I’m just frustrated, I feel like at the very least everything I provided would be enough for probable cause but obviously I’m not very knowledgeable on anything related to this and just wanted a second opinion.

I understand that an arrest isn’t automatic and that an eventual conviction would require a much higher burden of proof. I’m specifically wondering about the investigative/probable-cause stage. Is there something about this process I’m misunderstanding?

Thank you ????????
