This Augmented Reality App Aims to Solve Cold Cases — and Change How True Crime Stories Are Told
  • CrimeDoor, an immersive augmented reality app launched last week, is straddling the space between mystery entertainment and crowdsourced crime solving.
  • The app was conceived by Neil Mandt, a longtime film and TV producer-turned-tech entrepreneur. A true crime enthusiast himself, Mandt said he saw an opportunity to merge the popular genre with immersive reality.
  • The AR environments are constructed based on real crime scene photos, police reports and eyewitness accounts.

A new augmented reality app launched this week allows anybody to feel what it's like to explore a murder site as it appeared right after the crime occurred. They may even be able to help crack an unsolved crime.


The app opens onto a map that shows users historic crime scenes in their area, using GPS data. Each crime comes with a case file that includes a list of articles, documents, photos, audio clips and videos curated by crime journalists and researchers that is meant to provide an organized synopsis of "the 5 w's and h."

CrimeDoor was conceived by Neil Mandt, a longtime film and TV producer-turned-tech entrepreneur. A true crime enthusiast, Mandt said he saw an opportunity to merge the popular genre with immersive reality, an industry he's been increasingly involved in over the last few years and which he believes is "on the verge" of explosive growth.

The AR environments are constructed based on real crime scene photos, police reports and eyewitness accounts using CrimeDoor's patent-pending technology and Unity, a gaming engine.

Users can explore the crime scene using their mobile devices at the real, physical location when feasible, or with a joystick navigator from their own home. They'll see the scene as it was reconstructed, and can "pick up" evidence and enlarge it on their screens for closer inspection.

At launch, the app will contain about 500 cases and dozens of virtual doorways, Mandt said. Cases are free, but the app charges $1.99 to enter a door, or a monthly fee of $4.99.


Some of the cases are famous, such as the murder of OJ Simpson's former wife Nicole Brown Simpson or the shooting of John Lennon. But, Mandt said, most will not be as familiar.

One such case is that of Rebecca Zahau, a woman whose 2011 death in Coronado, California was ruled a suicide. The family contested the cause of death and filed a wrongful death lawsuit. Zahau's family has provided CrimeDoor with materials such as court documents and autopsy photos. A perpetrator was charged in a civil trial – not a criminal one – and Mandt said the family wants to bring the case back to light and give the public a chance "to look at it."

Mandt also noted he has heard great feedback from both user test groups and law enforcement agencies.

"The average detective has one hour on a crime scene and later a couple of photos and a matchstick and a hairy sock," Mandt said. "We have shown this to the FBI and law enforcement departments and without exception everyone compared it to DNA. The way DNA changed the game, this will do the same."

According to a company representative, a retired criminal investigator who helped to solve the infamous Golden State Killer case called CrimeDoor "a game changer for cold cases around the world."

UCLA law professor Eugene Volokh, who has studied and written about the intersection of AR/VR and law, told dot.LA that CrimeDoor should be wary of potential issues such as libel or needlessly upsetting a victim's family members. He emphasized, however, that such concerns are no different than those faced by any true crime storyteller, regardless of the medium.

"Generally, there are no legal or ethical problems raised by an AR or VR app as opposed to a documentary or a book," he said.

Mandt, who is self-financing the app, sees partnerships with media companies as a big opportunity for future growth. He said an organization with legacy crime footage, such as "60 Minutes," could partner with CrimeDoor to build out the AR crime portal, re-air the legacy footage on television, then direct viewers to the app and share a cut of the income.

"I'm interested in where the social web goes and how other AR leaders come to us and say here's how we can collaborate," he said. "The tech community, I'm excited to see what kind of creative things they can do with this. And Hollywood – producers will look at this and come to us."

Mandt also hinted at potential expansion by augmenting the user experience with sounds and technology that stimulates a user's sense of touch. He's also considering adding a marketplace to sell merchandise and implementing a credit-earning system to allow for add-on experiences, such as a ride-along in the OJ white Bronco highway chase.

    Down the line, CrimeDoor may incorporate advertising, Mandt said. The app may also eventually incorporate premium content, such as access to movies, shows and books related to a given case.

    LA’s Upgrade in Travel and NBA Viewing

    🔦 Spotlight

    Exciting developments are underway for Los Angeles as the city prepares for major upgrades in both travel and entertainment. The Los Angeles Board of Airport Commissioners has approved an additional $400 million for the Automated People Mover (APM) at LAX, increasing its total budget to $3.34 billion. This boost ensures the elevated train’s completion by December 8, 2025, with service starting in January 2026. For Angelenos, this means a significant improvement in travel convenience. The APM will streamline connections between parking, rental car facilities, and the new Metro transit station, drastically cutting traffic congestion around the airport. Imagine a future without the dreaded 30-minute traffic delays at LAX! The APM will operate 24/7, reducing airport traffic by 42 million vehicle miles annually and carrying 30 million passengers each year, while also creating thousands of local jobs and supporting small businesses.

    Meanwhile, the NBA is also making waves with its new broadcasting deals. The league has signed multi-year agreements with ESPN, NBC, and Amazon Prime Video, marking a notable shift in media partnerships. ESPN will maintain its long-standing role, NBC returns as a network broadcaster after years away, and Amazon Prime Video will provide NBA games through its streaming platform. Starting with the 2025-2026 season, these deals will enhance the league's reach and revenue, aligning with the NBA's goal to expand its audience and adapt to evolving viewing habits. Whether you're catching the action on TV or streaming online, these changes promise to elevate the fan experience and bring more basketball excitement to Los Angeles.

    🤠Musk Picks Texas and 🔥Tinder AI Picks Your Profile Pictures

    🔦 Spotlight

    Tinder is altering dating profile creation with its new AI-powered Photo Selector feature, designed to help users choose their most appealing dating profile pictures. This innovative tool employs facial recognition technology to curate a set of up to 10 photos from the user's device, streamlining the often time-consuming process of profile setup. To use the feature, users simply take a selfie within the Tinder app and grant access to their camera roll. The AI then analyzes the photos based on factors like lighting and composition, drawing from Tinder's research on what makes an effective profile picture.

    The selection process occurs entirely on the user's device, ensuring privacy and data security. Tinder doesn't collect or store any biometric data or photos beyond those chosen for the profile, and the facial recognition data is deleted once the user exits the feature. This new tool addresses a common pain point for users, as Tinder's research shows that young singles typically spend about 25 to 33 minutes selecting a profile picture. By automating this process, Tinder aims to reduce profile creation time and allow users to focus more on making meaningful connections.

    In wholly unrelated news, Elon Musk has announced plans to relocate the headquarters of X (formerly Twitter) and SpaceX from California to Texas. SpaceX will move from Hawthorne to Starbase, while X will shift from San Francisco to Austin. Musk cited concerns about aggressive drug users near X's current headquarters and a new California law regarding gender identity notification in schools as reasons for the move. This decision follows Musk's previous relocation of Tesla's headquarters to Texas in 2021.
