(CNN) - Fifteen days after the Boston Marathon bombings, Massachusetts voters head to the polls Tuesday to select Democratic and Republican nominees in a special U.S. Senate election that's been almost completely overshadowed by the terror attacks.
Even before the bombings, Massachusetts voters weren't paying that much attention to the contest to fill the remaining year and a half of the term of longtime Democratic Sen. John Kerry, who stepped down earlier this year to become U.S. secretary of state.
CNN: Boston probe eyes slain Canadian jihadist, source says
Federal agents are looking into possible links between dead Boston Marathon bomb suspect Tamerlan Tsarnaev and a Canadian boxer-turned-jihadist killed by Russian troops in 2012, a source being briefed on the investigation said Monday. William Plotnikov and six others died in a firefight with Russian forces in the southwestern republic of Dagestan in July 2012, while Tsarnaev was visiting the region, the source said. The 23-year-old Plotnikov was born in Russia, but his family moved to Canada when he was a teenager. The source said Plotnikov's body was prepared for burial by a local imam on July 14. Tsarnaev flew out of Dagestan two days later, arriving in New York on July 17. Investigators are looking into the possibility he left because of Plotnikov's death, the source said.
