The Bexar County Sheriff’s Office is moving forward with an expansion of a jail-based intelligence operation that analyzes inmate communications for investigative leads made possible by a $2.6 million earmark in the federal budget.
The effort, tentatively called the Law Enforcement and Detention Intelligence Network, or LEAD-IN, would allow the sheriff’s office to purchase software to transcribe, search and analyze inmate phone calls and other jail-linked records at a larger scale — building on intelligence work that is already underway inside the Bexar County Jail.
Sheriff Javier Salazar said the goal is to use technology to amplify their ability to process more information at once.
“We don’t make any secret of it, 5,000 inmates is a treasure trove of information on the crimes that got them in the jail, but also other crimes that are ongoing out in the community,” he said. ”They may be discussing drug trafficking rings that they’re still involved in, talking about murders that they know about, or the location of a body that we haven’t found yet.”

Existing unit, expanded tools
The proposed expansion would not create a new unit or include any new hires. It would be built around an existing detention intelligence team already doing gang intelligence and investigations work inside the jail. That team already monitors inmate phone calls, reviews recordings and develops intelligence related to gang activity, contraband, threats inside the jail and investigations outside of the facility.
Sgt. James Ma, who works in the jail intelligence unit, told commissioners during a Feb. 3 presentation that investigators are often faced with a large volume of information tied to each criminal case — which can include thousands of phone calls, messages and digital records tied to a single investigation.
The LEAD-IN program, he said, is intended to reduce the time it takes to sort through that material, allowing analysts to identify potential leads more quickly and pass them on to investigators in the field.
The unit has already seen success using intelligence to disrupt serious criminal activity, said Deputy Chief Angela Freveletti, who oversees the unit, pointing to a recent murder-for-hire plot that was uncovered through inmate communications and led to five arrests inside and outside of the jail.
“In this recent case, one inmate was soliciting other inmates to find people from the outside that could possibly hurt or harm a witness in their case,” she said. “ We were able to get on top of that, put a case together and make arrests.”
She added that LEAD-IN has been designed to build on that kind of work while assisting to close the loop on any information that could be missed due to the grand scale of information that is being reviewed.
“We don’t know how much of this information we’re actually missing because we can only do so much with the things that we have at our disposal,” Freveletti said. “We’re catching a lot of really good stuff, but how much of it are we catching? Is it a tip of the iceberg type of thing? With the money, we’re able to invest in the latest and greatest software out there and we’re hoping that we’re gonna be able to catch a lot more of these tips.”
While LEAD-IN is centered inside the jail, it is intended to generate investigative leads beyond it. Salazar said information developed through inmate phone calls or jail-linked records is routinely shared with outside law enforcement agencies, including the San Antonio Police Department, the Bexar County District Attorney’s Office and federal partners, when relevant to ongoing cases.
“It’s not uncommon for the DA’s office, SAPD, Drug Enforcement Agency or anybody to come to us and say, ‘Hey, you’ve got a certain person in jail, what are they saying? Who are they talking to on the phone? Are they talking about an escape? Are they talking about this murder that happened?” Salazar said. “You’d be surprised what some of these folks will say.”
Freveletti said the technology could also assist investigations involving missing or endangered persons, particularly when time-sensitive digital data must be processed quickly. Thousands of points of data can be retrieved from cellphones and other electronics in missing persons cases, but it can be a time intensive process if you don’t have the right software, she said.
“Our hope is, especially with the missing persons, that we’re able to mine that data a lot quicker, so that we can locate people quicker,” Freveletti said. “Especially if they’re in any type of danger or dealing with some type of mental health crisis, the software is going to help us a lot.”
Commissioners raised questions during the discussion about civil liberties, data ownership and oversight.
Salazar said inmate communications — excluding attorney-client calls — are already recorded and monitored, and that inmates are warned of that fact each time they place a call from the jail.
“Inmates really have no expectation of privacy on those calls,” Salazar said. “If you’re talking on the phone, while you’re an inmate in the jail, that’s really on you at that point, because it’s pretty well known that we do this, and even then, we’re still catching stuff.”
Salazar and other officials stressed that LEAD-IN would rely on records lawfully obtained by the sheriff’s office and is not intended to monitor civilians or collect information unrelated to criminal investigations. Some tools would require warrants signed by a judge, depending on the type of data involved, while other detention intelligence does not.
“The last thing we want to do is violate civil rights,” he said. “At that point, we’re no better than the crooks we’re trying to put in jail.”
The $2.6 million earmark was approved as part of federal appropriations legislation passed last month and does not require county approval. Salazar said it could take 12 to 36 months before the sheriff’s office receives the funding.

After the grant funding is exhausted, the sheriff’s office would need to justify whether to continue the program within its department budget that exceeded $200 million in fiscal year 2026.
“Literally anything and everything that this intelligence touches is going to be tracked as a stat,” he said.” All the weapons or contraband found within the jail. How many drugs were recovered from within the jail? How many cases did it affect on the outside? Did we solve any murders? Did we break up any human trafficking rings?”
