 Police in El Cerrito are asking for the public's help to catch a woman they say is a violent suspect who may get caught because of her own mistake. And the case may be cracked by a selfie.According to authorities, the smiling woman in the selfies is actually a violent thief who beat up a teenage girl to steal the phone that took these pictures.A young El Cerrito High School student was walking to class talking on her iPhone when a car rolled up and a woman jumped out and demanded her phone and backpack and then started punching the girl."She hit the juvenile in the head several times causing some minor injuries to her facial area," said Sgt. Ian Wong. And actually caused her to lose consciousness and go to the ground."Several days later, while recovering from her injuries, the young victim found the selfies on her iCloud account and recognized the woman as her attacker."I don't think she knew it was being uploaded to the cloud. I think they were assuming it was on the factory default settings," Wong said.Students say nearly everyone has a smartphone, but some protect them better than others.While one student said she probably wouldn't do anything different, student Devin Emelo said, "Don't like be showing and trying to be flashy with your phone and stuff like that. Stop showing people you have nice stuff, because people might be wanting the stuff that you have."As for the woman who snapped those incriminating selfies, another student said, "That's kinda dumb to take pictures of yourself." ||||| Authorities are hoping to find new clues in the Boston Marathon bombing case by poring over a laptop belonging to one of the suspects and learning what the other told his wife in a phone call days after the blast, sources told ABC News. 
 
 Robert Stahl, an attorney for a friend of bombing suspect Dzhokhar Tsarnaev, said his client had taken Dzhokhar's laptop from his room but turned it over to the FBI "the very first time" agents came to see him late Friday, four days after the bombing. 
 
 Stahl's client, 19-year-old Dias Kadyrbayev, was charged along with another 19-year-old friend with conspiracy to obstruct justice for taking the laptop and allegedly trying to dump a backpack full of fireworks -- which had been emptied of their powder -- also belonging to Dzhokhar after they realized Dzhokhar was involved in the bombing. After the teens' court appearance Wednesday, Stahl denied his client knew Dzhokhar was involved in the attack at the time and said Kadyrbayev did not think the items were of evidentiary value. 
 
 A law enforcement official also told ABC News today that the FBI is seeking to find out what the other bombing suspect, Dzhokhar's older brother Tamerlan Tsarnaev, told his wife in a phone call shortly after the FBI released his photo to the public three days after the attack. The official said only the woman, Katherine Russell, knows the content of the conversation. 
 
 Russell's attorney said in a statement Tuesday that she was providing "as much assistance to the investigation as she can." 
 
 Tamerlan and Dzhokhar Tsarnaev are accused of planting two bombs near the finish line of the Boston Marathon on April 15. When the bombs exploded, three people were killed and more than 260 others were injured. Three days after the bombing the FBI released surveillance images of the suspects, who they had not yet identified, in hopes the public may be able to track them down. Hours later, Tamerlan was killed in a firefight with police. Dzhokhar escaped for a while but was injured and eventually caught on April 19. 
 
 Terrel Harris, a spokesperson for the Massachusetts Office of the Chief Medical Examiner, told ABC News that Tamerlan's body will be released from his office today to Tamerlan's family. 
 
 Wednesday authorities arrested three 19-year-old friends of Dzhokhar's: Dias Kadyrbayev and Azamat Tazhayakov, both students originally from Kazakhstan, and American Robel Phillipos. In addition to the conspiracy to obstruct charges against Kadyrbayev and Tazhayakov, Phillipos is charged with lying to federal investigators. 
 
 Attorneys for the Kazakh students said their clients had nothing to do with the bombings, and they disputed parts of the criminal complaint against their clients. An attorney for Phillipos reportedly said his client was not connected to the bombing or to the Kazakh students' actions and downplayed his client's alleged lies as "misrepresentations." 
 
 Charging documents filed Wednesday against Dzhokhar's friends revealed new details in the case, including an exchange that took place a month before the attack in which Dzhokhar allegedly bragged that he knew how to build explosive devices. Dzhokhar also allegedly responded to one of his friends who asked if was the suspect shown in FBI photos with "LOL."

– People just don't learn, do they? A woman who allegedly stole a high school student's iPhone in California has given police a break in the case thanks to … a selfie—or rather, several of them. Police say an as-yet unidentified woman approached the 15-year-old student in El Cerrito on Nov. 5, demanding that she hand over her phone and backpack, reports the Los Angeles Times. When the girl refused, the suspect allegedly knocked her unconscious with a punch, took the student’s phone, dragged her a short distance, then took the girl's backpack, per the Oakland Tribune. The woman then escaped in a tan Honda or Toyota which was also carrying four males, authorities say. Days later, the student, who had to visit a hospital for treatment, found several smiling selfies of her alleged attacker on her iCloud account and sent them to police. "I don't think she knew it was being uploaded to the cloud. I think they were assuming it was on the factory default settings," an officer tells ABC7. Authorities have released three images of the woman—which show many more selfies were taken—and say tips are pouring in. (Click for more ill-advised selfies.)
