Teacher: Now, understand the problem? Solve this instance: A judge sentenced a Pico Rivera man to nearly 40 years in state prison for extorting 21 underage girls in eight states into sending him nude pictures online, authorities said. 
  
 Cesar Mauricio Estrada-Davila, also known as Cesar Estrada, 20, pleaded “no contest” on Wednesday to 38 felony charges, including 21 counts of distributing or showing child pornography to a minor, 16 counts of possession of child pornography and one count of committing a lewd act on a child, Los Angeles County District Attorney’s Office spokesman Ricardo Santiago said in a written statement. 
  
 At his sentencing on Friday in the Antelope Valley branch of Los Angeles County Superior Court, Estrada received a prison term of 39 years and 8 months. He will also be required to register as a sex offender for the rest of his life. 
  
 “According to testimony at the preliminary hearing, Estrada reached out to young girls and befriended them on social media websites between January and April, 2015,” Santiago said. “The defendant told the victims he was a modeling agent who could make them famous online. 
  
 “Estrada then asked the victims to send him pictures of themselves in their underwear,” according to Santiago. “Once the defendant received the images, he would tell the girls he was going to send the photos to their friends and family if they did not send nude photos.” 
  
 Prosecutors filed charges in connection with 21 victims between the ages of 12 and 17 in the states of California, Nevada, Utah, Texas, Michigan, Washington, Colorado and Florida. 
  
 The investigation began after a 14-year-old Antelope Valley girl who reported the online extortion to her father, who in turn contacted police, sheriff’s Lt. Andrew Meyer said shortly after Estrada’a arrest. 
  
 Detectives searched Estrada’s home in the 8300 block of Rosemead Boulevard in Pico Rivera, where they found more than 26,000 pages of online and text conversations between Estrada and his victims, Meyer added. All of the victims were Latina girls, and many told investigators they had been living in fear of Estrada. 
  
 Estrada was initially charged with more than 150 crimes and could have received multiple life sentences if convicted at trial, prosecutors said.

A California man who posed as a modeling agent to extort nude photos from young girls across America has been sentenced to almost 40 years in prison—twice as long as he has been alive. Cesar Mauricio Estrada-Davila, 20, pleaded no contest this week to 38 felony counts, including 16 counts of possessing child or youth pornography, and was sentenced to 39 years and 8 months, CBS reports. Prosecutors say that for several months in early 2015, Estrada-Davila reached out to young girls he found on social media websites. He told them he could make them famous and asked for photos of them in their underwear, then threatened to show the underwear photos to their families and friends if they didn't send him nude photos. Estrada-Davila was charged in connection with 21 victims between the ages of 12 and 17 in eight states. Police say he was arrested after a 14-year-old California girl told her father about his demands, the San Gabriel Valley Tribune reports. Cops searched his Los Angeles County home and found more than 26,000 pages of text and online conversations between him and his victims. Before a plea deal was worked out, Estrada-Davila faced more than 150 charges, enough to send him to prison for life several times over.
