Lancaster County Sheriff's Office covers 550 square miles and more than 114,000 residents in South Carolina. Their investigations team runs hard every day — managing active cases, writing supplements, preparing for court, and staying on top of hundreds of jail calls that come in every month.
The challenge wasn't capability. It was capacity. No team, no matter how experienced, can listen to 767+ calls a month, transcribe every recorded interview, and manually comb through every case file while running a full division. Something was always going to go unreviewed.
Captain Jennifer Rumbaugh, who leads investigations at Lancaster County, knew this wasn't a skills problem. It was a volume problem.
A woman connected to a shooting was brought in for an interview. At some point during the session, the detective stepped out of the room. While alone, she had a conversation with her mother, and in that conversation, she disclosed details about the shooting and revealed information about the location of the gun.
No investigator was in the room. No one caught it in real time.
The interview was uploaded into TRULEO as part of the standard case workflow. TRULEO processed the full recording and flagged the conversation that happened during the break.
"We did not know about it until we put this interview in TRULEO, and it brought it to our attention." - Captain Jennifer Rumbaugh, Lancaster County Sheriff's Office
One upload. One analysis. A piece of investigative intelligence that would have otherwise gone undiscovered was now actionable, including the location of a firearm connected to an active shooting case.
Lancaster County's experience isn't unique. Investigations teams across the country are managing a growing volume of recorded content, including jail calls, inmate messages, recorded interviews, and uploaded case files. All of it carries potential intelligence. Almost none of it gets fully reviewed.
If your team is fielding 767 jail calls a month alongside active casework, court prep, and report writing, a meaningful portion of that content is going unheard. Leads go cold. Connections get missed. Cases that could close faster stay open longer.
TRULEO's jail call intelligence and case file analysis tools are built to close that gap, analyzing 100% of recorded content automatically, flagging relevant conversations, detecting inconsistencies, and surfacing leads that manual review would miss. The result is the kind of investigative coverage that helps teams increase clearance rates and close cases faster, without adding headcount.
The shooting case is one moment in a much broader daily workflow. TRULEO is now embedded across how Lancaster County investigators and deputies operate, from the first day of a case to the moment they walk into court.
Jail Call Intelligence: 767+ calls analyzed in April alone. Every call reviewed automatically. Relevant conversations, threats, and intelligence surfaced without anyone spending hours manually listening.
Uploaded Interviews and Case File Analysis: Recorded interviews uploaded for full analysis. Key statements identified, inconsistencies flagged, intelligence surfaced, including content captured during informal moments investigators weren't present for.
Supplemental Report Generation: Investigators upload recorded interviews and TRULEO generates supplements directly, eliminating manual transcription and cutting hours from the documentation process.
Evidence Analysis and Case Summaries: Complex case files summarized quickly, timelines built, and connections identified without investigators manually cross-referencing hundreds of pages.
Court Preparation: Case materials organized and prosecutor-ready. Relevant statements surfaced and chains of evidence documented before investigators walk into the courtroom.
Report Writing: Deputies using TRULEO for report writing after calls, reducing documentation time and keeping officers in the field longer.
"TRULEO allows us to quickly surface meaningful intelligence from an overwhelming volume of calls. We can identify relevant conversations, detect inconsistencies, and capture key statements in minutes. That level of visibility has materially improved the speed and quality of our investigations." - Captain Jennifer Rumbaugh, Lancaster County Sheriff's Office
TRULEO didn't get adopted at Lancaster County because it was required. Investigators and deputies started using it, saw what it could do, and built it into their daily workflows on their own.
Over time, Captain Rumbaugh noticed her team getting sharper. Deputies became increasingly precise in how they prompted the platform, unlocking more value with every use. That kind of precision doesn't come from a one-time training. It comes from a team that keeps showing up and keeps finding new ways to get more out of the tool.
"We all love it and know that we are just scratching the surface of using it. Excited to onboard and continue to grow with it." - Captain Jennifer Rumbaugh, Lancaster County Sheriff's Office
Lancaster County is moving to full agency deployment in July 2026.
The evidence in this case didn't appear out of nowhere. It was already in the file, and it had been there since the interview ended. What changed was that Lancaster County uploaded it into TRULEO, and TRULEO found what no one knew was there.
