One of the most daring ways to track suspected criminals is to use a text message to tell them that they are wanted and encourage them to be self-employed. But the US Secret Service has made this a success. In April of this year, a person named Abdul Inusa was charged with romance fraud in West Virginia. Inusa is said to have created various fake figures online, tricked people into building relationships, and robbed them of money. In one case, Inusa had the victim believe that she was a woman named Grace and owned a cocoa plantation in Johannesburg, South Africa, and sent her money to maintain the plantation. The Secret Service chief investigator sent the text to a phone number believed to belong to Inusa. At first, “Mr. Inusa, please call me if you have a chance”, but then I sent “I have an arrest warrant from Huntington, Wisconsin, so I want you to appear.” It was. Then, he received a phone call from a lawyer who said he had received a request from Inusa. The lawyer eventually turned down Inusa’s defense and handed it over to a colleague, who allegedly turned down his defense by calling an investigator. However, the investigator was convinced that the phone number he sent the text to was actually Inusa’s and until recently he was using it. I also got an iPhone notification that the text was read. Shortly thereafter, investigators obtained mobile phone location information from Verizon, but the data was not accurate enough. Two weeks after sending the text, the Secret Service considered Inusa a fugitive and was concerned that he, an illegal immigrant, would flee abroad. They ordered what was called E-911 Phase II data for more precise location information. This data, managed by carriers, is primarily used by paramedics, but can be used by law enforcement agencies in investigations. Investigative tool to extract location information Also requested the judge to use an investigative tool called “Stingray”. This tool is used to trick a cell phone into pretending to be a base station and believing that it is connected to a nearby base station. You can use it to get accurate location information for connected mobile phones. However, Stingray has been controversial in the past. Even if the police promise to minimize the impact, they will even suck up the data of innocent people. Senator Ron Wyden of Oregon recently submitted a bill requiring all law enforcement agencies wishing to use Stingray to first obtain appropriate warrants with justification. Court documents do not say whether the use of these tools was successful, but confirmed that Inusa was arrested on June 16 and paid $ 10,000 on bail. His lawyer has not responded to Forbes’ request for comment.
