The tip came in on a Thursday morning, telling police about a drug house in the 1200 block of North Jackson.
The information was relayed to patrol officers. As they pulled up just after 12:30 p.m., two 19-year-old men bolted from the house.
The officers quickly arrested them, along with the woman who owns the house. Officers found "tens of pounds" of marijuana worth "tens of thousands" of dollars, officials said.
The incident has become a benchmark for Crime Stoppers, because the tip came in Spanish on a tip line dedicated to that language.
Never miss a local story.
"That's a big one," said Jim Todd, chairman of the Crime Stoppers board. "We've been trying to get some inroads into the Hispanic community."
The tip came only a few days after Crime Stoppers leaders met with a group of residents at St. Patrick Catholic Church, near 21st and Arkansas, to talk about crime trends and stress that tips called in to Crime Stoppers are confidential.
Wichita police Detective Hans Asmussen, who works with Crime Stoppers, said it's impossible to know whether that Sunday meeting prompted the phone tip because the calls are anonymous.
Like many people not familiar with how Crime Stoppers works, Todd said, Hispanics have been leery of calling in tips "because they're afraid they'll somehow be found out."
On top of that, he said, some are afraid investigators may learn that the tipster — or someone related to the tipster — is not in the country legally, and they'll be deported.
"We work hard to get around that" perception, Todd said. "That's not our business."
Crime Stoppers has had a Spanish-language line — 409-STOP — for several years. Asmussen said the organization will keep it even though the 24-hour call center now receiving tips can handle calls in Spanish.
The line has also been available for Spanish-speaking residents to check on the status of cases, and Asmussen said he wants to take advantage of the recognition of the number that has increased over time.
Building trust with the Hispanic community hasn't been easy for local law enforcement, which is why Crime Stoppers can play such an important role, said Dan Oropesa, who recently joined the organization's board of directors.
"In Mexico, sometimes, the police are part of the problem," Oropesa said. "In certain parts of the world, they're not always there to serve and protect."
To counter that cultural distrust, Oropesa said, Crime Stoppers leaders have been stressing the importance of safety to families and neighborhoods.
Crime Stoppers, Oropesa said, "is how the folks can protect their families and protect their neighborhoods in a safe way.
"They're concerned about their families, they're concerned about their neighborhoods."
Crime Stoppers printed up about 29,000 postcards in Spanish and English explaining how the technology allows calls to remain anonymous, whether it's by phone, text or the Internet, Todd said.
The cards have proven so popular that the organization will soon need to print another batch, he said.
"I think you'll see more activity as a result of them feeling more comfortable," Oropesa said. "It's a way they can say, 'We don't want this in our neighborhood,' without reprisals from these criminals as well as some mixed feelings about authority."
That progress won't be easy to chart, he said, though the drug bust on North Jackson ranks as a milestone.
"All you can do is take benchmarks along the way," Oropesa said. "I think this is a very, very good start."
