A Chicago police spokeswoman says detectives are questioning two men she describes as "persons of interest" in the fatal shooting of 15-year-old girl in a South Side park.

Spokeswoman Melissa Stratton says the two men, ages 18 and 20, were taken into custody early Sunday morning. She said no charges have been filed.

First lady Michelle Obama and several other dignitaries attended the funeral of Hadiya (hi-DEE'-uh) Pendleton on Saturday.

Pendleton was shot to death Jan. 29 about a mile from President Barack Obama's home on the city's South Side. Police say the shooter mistook someone in the group Pendleton was standing with as a member of a rival gang.
