"Whatever our findings, they won't be pretty. There is no way they can be under these circumstances. They won't be pretty, but they will be honest."
State police. meanwhile, have taken over handling the investigation from the Detroit police.
"Due to the fact that the family of Aiyanna Jones has apparently retained legal counsel, along with the fact that the investigation…..has been handed over the Michigan State Police, the City of Detroit Law Department has advised the Detroit Police Department to refrain from giving any further comment on this investigation at this time," Assistant Chief Ralph Godbee said in a statement.
Fieger says there were 15 officers present during the raid and he called on the officers who witnessed the incident to come forward with the truth about what happened.
"You all know what happened at this scene. Please don't let this child have died in vain," he said.
Fieger filed federal and state lawsuits on behalf of the family Tuesday alleging violation of civil rights, gross negligence and conspiracy to hide what actually happened.
A tearful Mertilla Jones also spoke at the news conference. She disputed the police account that she fought with an officer. "As soon as they hit the window, I hit the floor and I went for my granddaughter," she said.
A spokesman for "The First 48" tells ABC News they had a camera crew along with the Detroit police. They were not filming inside the home. The spokesman said A&E is cooperating with the investigation.
Fieger would not say who brought the tape to him but said he's not sure whether or not A&E has video. Fieger seemed to suggest the Detroit Police Department was also videotaping the incident.
Citizens and government officials across Detroit have expressed outrage at the little girl's death.
"We just can't continue to accept this kind of massacre of our citizens in the city of Detroit. Can't do it," Detroit Mayor Dave Bing told ABC station WXYZ. "The bottom line is we've got a young 7-year-old kid that's been killed. We all ought to be outraged by that."
The Detroit Coalition Against Police Brutality said, "The details of this tragedy represent something that we've never seen before. The use of an incendiary device, and the shooting of the 7-year-old in the middle of the night can only be described as the 'pain of pains.'" The coalition said it wants to know what police protocols and procedures were used in the raid.
