CBS News Miami gets rare access to MDPD’s forensic lab where gun crimes are solved


MIAMI – CBS News Miami visited the Miami-Dade Police Headquarters to investigate how local authorities solve gun-related crimes, following a report from our sister station in Minneapolis about delays with the ATF’s E-trace system.

While the E-trace system has caused case delays elsewhere, Miami-Dade Police use advanced forensic science and a national database to develop investigative leads.

CBS News Miami was given rare access to the department’s forensic lab to see how their process works.

The first room on our tour was the shooting lab, where firearms recovered from crime scenes are tested. The gun we saw was used as part of a simulated mock crime scene event to illustrate the entire process. After the specialist in the shooting lab loaded the gun, he put the firearm in position to fire into a specialized water tank.

“The water slows down the bullets so we can recover it, and use the markings on that bullet and compare to any evidence that’s recovered,” shared Gabriel Hernandez, who helps lead the lab at Miami-Dade Police Headquarters.

He’s worked there for 19 years, overseeing a group that’s generated thousands of leads to help solve Miami-Dade criminal investigations.

“If there’s a gun that’s been recovered, then the main question is, is this the gun that fired those casings and/or bullets,” shared Hernandez.

The mission: match the firearm with the ammunition recovered.

After the test bullets were fired, we moved to a different lab section with microscopes. Under a microscope, we saw how they closely examined test-fired bullets from the shooting tank compared to one recovered from our mock crime scene.

“And then compare those markings on those two items under one field of view,” added Hernandez.

“Markings all along the edge here are a signature of that firearm, unique to that firearm much like a fingerprint is to a person.”

In this case, we saw it was a perfect match.

However, in real cases, detectives do not always recover a gun from a shooting investigation, or the ballistic evidence collected does not match the firearm found.

When that happens, the department turns to technology known as NIBIN. It stands for the National Integrated Ballistic Information Network, run by the federal government.

This national computer database stores recorded ammunition markings from evidence collected at crime scenes nationwide for comparison.

In this part of the lab, we witnessed them taking a bullet and inserting it inside a computer that then scans it into the database for record keeping.

“We have thousands and thousands of images in the system,” said Hernandez. “It captures those images, and then they’re compared to the entire database of all the casings and all the other test fires that we’ve entered into the system. The database sends back a list of potential matches.”

A trained forensic expert then compares the markings on a computer to see if there’s a match to other ballistic evidence collected from another crime scene, helping to solve other investigations.

They can process the evidence that’s been cleared and submitted to the lab in just a few hours.

MDPD shared this statement with us:

“In 2001, the Miami-Dade Police Department started imaging casings in the National Integrated Ballistic Information Network (NIBIN), which is run by the ATF. Prior to that, casings were imaged in DRUGFIRE, a system run by the FBI. Currently, there are over 11,000 NIBIN leads from casing evidence entered at the MDPD Forensic Services Division Crime Laboratory. Approximately 600 NIBIN leads have been made since the beginning of 2024.”

Penn State transfer portal target, Pa. native commits to Miami

Penn State transfer portal target, Pa. native commits to Miami


Penn State had a successful Saturday, beating SMU in the College Football Playoff first round in convincing fashion. But not everything went the Nittany Lions’ way.

David Blay, one of Penn State’s top targets in the transfer portal, committed to Miami. The news was reported by on3 on Saturday afternoon.

In addition to Penn State and Miami, Blay was also being pursued by Florida State, Illinois, Oklahoma, USC, Wisconsin, Mississippi State and Arkansas.

Blay, a standout at Louisiana Tech who visited last weekend, was a top target for the Nittany Lions as they look to add depth and talent to their defensive line for the 2025 season.

Blay is a Levittown native who played at Harry S. Truman High School outside Philadelphia before going to West Chester to play at the Division II level in 2021 and 2022. Blay transferred to Louisiana Tech, where he was a first-team All-Conference USA selection this year.

Blay finished the 2024 season with 46 tackles, 10 1/2 tackles for loss and 6 1/2 sacks.

Penn State has addressed a couple needs in the portal so far in the winter window, earning commitments from USC wide receiver Kyron Hudson and Texas A&M defensive end Enai White. But the Nittany Lions would love to add a defensive tackle or two.

Miami Heat Sharpshooter Could be Perfect Fit for OKC Thunder

Miami Heat Sharpshooter Could be Perfect Fit for OKC Thunder


Throughout the season, Oklahoma City has had struggles shooting from outside, and a fix could come through the trade route.

On Friday, the Thunder won their seventh straight regular season game with a 104-97 victory in Miami. The Thunder improved to 22-5 and had one of their best 3-point shooting nights of the season, shooting 14-of-34 from outside. 

On the other side, the Thunder might have played against someone who could be a seamless fit. Heat forward Duncan Robinson had a rough shooting night against the Thunder, as most players in the league do, but kept firing for a 3-of-11 night from beyond the arc.

A career 39.7% 3-point shooter, Robinson has hit near that mark again this season while taking well over six attempts per game. Although his defense has been criticized throughout his career, he has shown he can play well enough to stay on the floor and contribute, as seen by his roles in Miami’s 2020 and 2023 Finals runs.

As far as the trade block, the Thunder have already been linked to Brooklyn’s Cam Johnson. While he and Robinson have a similar contract, Johnson has one more year on his deal and makes a bit more money. 

While Johnson’s added production makes him clearly the better player and potential target, the Thunder might be able to get Robinson for a much lower price, especially if the Heat begin to shift gears and go through with a Jimmy Butler trade.

In any case, the Thunder would have to send out someone in the rotation. Given what Robinson could bring to the Thunder, players on newly signed extensions, such as Isaiah Joe or Aaron Wiggins, could be the perfect centerpiece of a deal alongside another small contract.

Given their youth, skillsets, and long-term security, either could be a solid piece for the Heat. Meanwhile, this would be a win-now move for the Thunder, losing one of the young wings they’ve developed for a proven playoff performer. 

Perhaps the Thunder would be hesitant to make such a deal after the Gordon Hayward trade went south last season. However, Robinson has been in and out of the Heat’s rotation throughout his time with Erik Spoelstra and could adapt to any role the Thunder throw at him.

There might not be a perfect trade for the Thunder, but Robinson could solve some problems and push the Thunder’s shooting into a championship tier.
