This undated photo found on the VK page of Dias Kadyrbayev shows Kadyrbayev, left, with Boston Marathon bombing suspect Dzhokhar Tsarnaev, at an unknown location. Kadyrbayev and Azamat Tazhayakov, two college buddies of Tsarnaev from Kazakhstan, were jailed by immigration authorities the day after his Tsarnaev's capture. They are not suspects, but are being held for violating their student visas by not regularly attending classes, Kadyrbayev's lawyer, Robert Stahl said.
The FBI said Saturday it had concluded its search of a landfill near the University of Massachusetts Dartmouth, where the 19-year-old suspect in the Boston Marathon bombings was a student.
FBI spokeswoman Laura Eimiller told the Associated Press the two-day search ended Friday, but would not say what investigators were looking for or whether any evidence was recovered. However, ABC News and other media outlets, citing law enforcement authorities, reported that the investigators in white hazmat suits are searching for a laptop tied to the accused bomber.
The lead emerged as a result of interviews with two men from Kazakhstan who knew the suspects, the sources told ABC News.
Dias Kadyrbayev, 19, and Azamat Tazhayakov, 20, were taken into custody a week ago on suspicion that they had violated their student visas by failing to attend classes. They are being held in a Boston jail, although a lawyer for one of the men said they have been interviewed by the FBI and are not considered suspects.
Murat Kadyrbayev, father of Dias, told the Kazakhstan website tengrinews.kz that the men "missed a couple or maybe several classes.
"I hope that American police will look into the facts and make the right decision. Most of the students who came in contact with Tsarnayev are being checked now; my son is not the only one. Nobody is an exception."
The men lived in an apartment near the campus of University of Massachusetts Dartmouth, where accused bomber Dzhokhar Tsarnaev had been enrolled.
ABC reported that Tsarnaev and his brother, Tamerlan, 26, were believed to have visited the New Bedford apartment after the bombing, according to three law enforcement sources, who spoke to ABC on the condition they not be named because they were discussing an ongoing investigation.
The police sources told ABC News they traced calls and Russian language text messages from one of the bombing suspect's cell phone to the Kazakhstani men.
"These kids are just as shocked and horrified about what happened as everyone else," Kadyrbayev's lawyer, Robert Stahl, told AP. "They can't even fathom something like this from a kid who seemed to be a typical young college student."
The Kazakh Foreign Ministry said said this week U.S. authorities came across the two while searching for "possible links and contacts" to Tsarnaev, a sophomore at UMass.
Dias' father confirmed to tengrinews.kz that the students from Kazakhstan owned a BMW with the vanity plate "terrorista" that was on a photo all over the Internet. He said that Dias and Azamat bought the car together some time ago.
Kadyrbayev said that the individualized license plate was a joke gift from their friends in Spain. "This joke led to trouble. But it was just a gag of their Spanish friends, just a gift."
Two explosions near the finish line of the Boston Marathon on April 15 killed three people and wounded more than 200. Dzhokhar Tsarnaev, 19, is charged with setting of the blasts along with his brother, Tamerlan, who was killed in a shootout with police days after the blast.
