The Chicago Tribune reports that more than 2,500 mourners walked past the caskets of Jennifer Hudson’s mother, brother and nephew. Hudson rose and spent a few minutes with each family member, attendees said, shortly before the service began.

The actress and singer stood at her mother’s casket and then leaned down and kissed her goodbye.

The invitation-only event required all guests have their names on a list and a light blue ticket with “Hudson Family Funeral” printed on it. Police blocked side streets around the church to keep reporters and fans away. Celebrity guests such as Oprah Winfrey, singer Fantasia Barrino, rapper Missy Elliot, actress Queen Latifah and record producer Clive Davis arrived through a private entrance.

Rev. Jesse Jackson spoke at the funeral. American Idol finalist George Huff also sang.

Police are investigating if more than one person was involved in the tragic murders of Jennifer Hudson’s mother, brother and nephew.

Investigators are trying to determine whether another person drove William Balfour to the West Side of Chicago after the killings at the Hudson’s South Side home according to law enforcement sources.

Balfour allegedly drove his vehicle on the block of the Hudson residence at 7:00am on Friday morning, yet his car was found a mile away outside a Chicago high school.

A security video shows someone parked the car outside the school but investigators have been unable to identity the person. According to the time stamp on the video, the car was parked at 12:30pm, roughly a couple hours after the murders.

Police do know that Balfour didn’t use his car to travel to his girlfriend’s house, where he was arrested last Friday evening.

Balfour remains in custody for violations but no charges have been filed as of yet.
