The oldest continuously operating crime lab in the United States is the Los Angeles Police Department (LAPD) Criminalistics Laboratory, established in 1923.
Where exactly is the oldest crime lab in the U.S. located?
It sits at 1801 E. 1st Street, Los Angeles, CA 90033—right in downtown LA, where it’s been since day one. You’ll find it at coordinates 34.0409° N, 118.2162° W, smack dab in the middle of the city’s forensic science scene.
What makes Los Angeles a good home for this crime lab?
LA isn’t just big—it’s a hotbed for innovation in policing and forensic science. The lab’s downtown location puts it where urban crime trends meet cutting-edge tech. Close to major highways, airports, and top universities, it’s perfectly positioned to collaborate with researchers and stay ahead of the curve.

Who started the LAPD crime lab, and why?
It all started with August Vollmer, a guy often called the "father of modern policing." Back in 1923, when he was LA’s police chief, he pushed to bring science into law enforcement—pretty radical for the time. He took inspiration from Edmond Locard, the French forensic pioneer who’d opened the first crime lab in Lyon in 1910. Vollmer ran with Locard’s idea that "every contact leaves a trace," making it the foundation of forensic work at the LAPD.
How has the lab evolved since the 1930s?
By the 1930s, the lab was already turning heads with its work in ballistics, fingerprint analysis, and toxicology. Its methods became the gold standard, even influencing the FBI when they set up their own lab in 1932. Fast forward to today, and the place is packed with next-gen tech—think STR DNA analysis, 3D crime scene reconstruction, and digital forensics tools for cracking cybercrimes. Honestly, this is one lab that never stops modernizing.
Can I visit the LAPD crime lab?
Not exactly a walk-in kind of place. The lab runs Monday through Friday, 8 AM to 5 PM (holidays excluded), but tours? Only by appointment, and even then, just for accredited schools or law enforcement groups. If you’re interested, you’ll need to request a spot at least 30 days early through the LAPD’s official website.
What kind of cases does the lab handle today?
They’re busy—like, really busy. Every year, the lab tackles over 60,000 cases, from homicides and sexual assaults to property crimes. Their work often ends up in court, with experts regularly stepping into the witness box. And if you think that’s impressive, they’re also teaming up with UCLA and USC to build AI tools that could automate fingerprint matching and gunshot residue analysis. The future? It’s happening here.
Does the lab work with universities or other agencies?
Absolutely. The lab’s partnerships with UCLA and USC are just the start. These collaborations are all about pushing forensic science forward, especially with AI-driven tools. Beyond that, the lab’s reputation keeps it connected to agencies nationwide, making it a go-to resource for complex cases.
Are the lab’s old case files available to the public?
You won’t find them on a shelf at the local library. The lab’s archives—full of case files, photos, and vintage forensic gear from the 1920s—are a goldmine for researchers, but they’re not open to the public. If you’re doing serious historical research, you can request access through the LAPD’s Historical Research Unit. Just don’t expect to flip through them like a history book.
Who’s running the lab right now?
As of 2026, the lab is led by Dr. Margaret "Maggie" Chen. She’s not just the first woman at the helm—she’s also the first Asian-American director. Breaking barriers? Check. Leading a team of forensic experts? Also check.
How does the lab stay accredited and up-to-date?
A big part of that comes from its accreditation by the American Academy of Forensic Sciences (AAFS), which it’s held since 2001. But staying current? That’s a constant effort. The lab invests in new tech, partners with universities, and regularly updates its methods to keep pace with the latest in forensic science. It’s not just about keeping the lights on—it’s about staying ahead.
What’s the biggest challenge the lab faces today?
One word: backlog. With over 60,000 cases a year, keeping up is a massive task. Then there’s the pressure to integrate new tech without disrupting ongoing work. And let’s not forget the need for funding—grants from city, state, and federal sources keep the wheels turning, but securing them isn’t always easy. Still, the team handles it all with impressive dedication.
How has the lab influenced forensic science nationwide?
Think of it as the granddaddy of U.S. crime labs. Its methods in the 1930s set the standard for ballistics, fingerprinting, and toxicology, and even the FBI took notes when they launched their own lab in 1932. Today, labs across the country still look to LA for best practices, making this place a quiet but powerful force in forensic science.
What’s the most surprising thing about the LAPD crime lab?
Here’s a fun one: the lab’s archives hold some seriously cool old-school forensic gear. We’re talking microscopes and cameras from the 1920s that look like they belong in a museum. But the real surprise? The sheer volume of case files—thousands of them, gathering dust but full of stories from decades of crime-solving. It’s a time capsule of forensic history.
Can the lab’s work be cited in court?
Without a doubt. The lab’s findings are routinely used in court proceedings, and its experts are frequent witnesses. Their work carries serious weight, thanks to the lab’s reputation for accuracy and reliability. If it comes from this lab, you can bet it’s going to hold up under scrutiny.
