A shooting in a Day Care center, are police changing their account of what transpired?

ROCKFORD, Ill. (CN) - Police officers chased an unarmed young man into a day care center and shot him in the head in front of 10 children after he surrendered, the children's parents and day care employees say in Federal Court. The families say the police then detained the kids, refused to feed them, lied to them, and tried to make them change their stories about what they had seen.
Guns drawn, Rockford police Officers Stanton North and Oda Poole chased 23-year-old Mark Balmore into the House of Grace Christian Learning Center in August, according to the complaint. Day-care workers said the officers pointed their guns "into a classroom full of children" as they sought Balmore for "alleged criminal activity."
(The Rockford Register Star reported that Balmore may have been involved in "two domestic disputes.")
Balmore hid in a basement equipment room next to the children's play area, and when he came out, unarmed, with his hands raised, the officers shot him once in the head and several times in the back, the day care workers said.
