Cedar Park Drug Bust Nets Guns, $44K Cash, and Three Suspects After Six-Month Investigation

A Single Tip Unraveled a Six-Month Investigation

It started with an anonymous phone call. In January 2026, someone reached out to Crime Stoppers with a tip about suspected drug activity in Cedar Park, Texas. Six months later, that single act of community vigilance led to a major drug bust, three arrests, and the seizure of an arsenal of weapons and tens of thousands of dollars in cash.

The Williamson County Sheriff's Office Organized Crime Unit spent months building its case, with the investigation culminating on July 6, when detectives served a search warrant at the Bexley Apartment Complex at 2801 S. Lakeline Blvd. in Cedar Park. What they found inside painted a picture of a significant local drug distribution operation.

What Investigators Found Inside the Apartment

During the search, detectives seized approximately 10.4 grams of cocaine, 25 ounces of THC wax, 1,208.4 grams of alprazolam pills, 772 grams of THC vape products, about 1.2 pounds of psilocybin mushrooms, and 50.56 pounds of marijuana. The sheer variety of substances suggests the operation was catering to multiple markets simultaneously — not just one type of drug buyer.

Investigators also recovered $44,522 in cash, a digital scale, and multiple cellphones, along with nine handguns, a Mossberg shotgun, three AR-15-style rifles, and a Draco AK-style pistol. The combination of high-powered rifles, handguns, and bulk narcotics points to an operation that was both well-armed and well-stocked — a serious public safety concern in a suburban community like Cedar Park.

Three People Arrested, Charges Filed

Arrested were Sergio Madrigal, 19, and Jessica Carrese, 20, who each face charges of manufacture and delivery of a controlled substance for cocaine, psilocybin mushrooms, alprazolam, and THC wax, along with possession of marijuana. A third suspect, Angel Rosas, 20, was charged with possession of a controlled substance related to THC vapes. All three suspects are young adults, raising questions about how deeply and how quickly individuals can become entangled in organized drug distribution.

All three suspects have since been released from jail — two on bond and one with dismissed charges. While the legal process is far from over for those still facing charges, the releases serve as a reminder that an arrest is not a conviction, and the judicial system will ultimately determine the outcome of the case.

Community Tips Remain a Powerful Tool

Sheriff Mike Lindemann credited detectives with dedication and perseverance in bringing the case to a conclusion, and the sheriff's office expressed appreciation for community members "staying vigilant, reporting suspicious activity, and working alongside us to keep our county safe." That sentiment underscores a broader truth about modern law enforcement: investigators can only act on what they know, and residents are often the first to notice when something is wrong.

The sheriff's office said the case underscores the Organized Crime Unit's commitment to dismantling narcotics trafficking operations in Williamson County.
