Two people died when a minivan carrying nearly 500 pounds of liquid methamphetamine crashed in a Fort Worth neighborhood, authorities reported.

The vehicle was found to contain the illegal drugs, which officials estimated to be worth up to $3 million. The crash occurred in a residential area of Fort Worth, though specific details about the location and circumstances leading to the accident have not been released.

Liquid methamphetamine is a form of the drug that is often used for transportation purposes, as it can be more easily concealed than crystalline forms. The substance is typically converted back to crystal form after reaching its destination.

Authorities have not yet released the identities of the two deceased individuals or provided information about whether they were occupants of the minivan or other parties involved in the incident. The investigation into the crash and drug seizure remains ongoing.
