A day after 15-year-old Hadiya Pendleton was laid to rest -- and 11 days after she was shot to death on the streets of Chicago -- police are questioning two people in relation to her slaying, a police spokeswoman said.
Chicago Mayor Rahm Emanuel called Hadiya's family on Sunday morning to tell them about the development in the investigation, said Chicago police spokeswoman Melissa Stratton.
No one has been arrested or charged yet in Hadiya's death, which occurred a week after she performed at President Barack Obama's second inauguration.
She was an honor student and band majorette at King College Prep School when a man shot her at a park in what her godfather, Damon Stuart, described as an "ideal community" on Chicago's South Side.
Police have told CNN affiliates that the teenager had no gang affiliation and likely was not the intended target.
Hadiya's performance at last month's inauguration and her death coming as the gun control debate brewed in Washington made her slaying a national story. She also was a standout student who urged friends to stay away from gangs.
