DETROIT -- A former employee for the Detroit Police Department, Joyce Carolyn Rogers, has sworn in an affidavit that she remembered exotic dancer Tamara Greene filing a police report claiming that Mayor Kwame Kilpatrick's wife, Carlita, had assaulted her during a party at the mayor's residence.

Rogers said in the affidavit that she worked as a senior clerk at police headquarters from 1997 until her December 2002 retirement.

According to Rogers' affidavit, she had remembered reading some interdepartmental mail that came across her desk in fall 2002. It was an envelope that contained a police report documenting an assault against Greene by Carlita Kilpatrick.

According to the affidavit, Carlita had witnessed Greene touching the mayor "in a manner that upset the mayor's wife."

The affidavit said that Carlita left the room and came back with a wooden object and began assaulting her. Two other men stepped in and tried to restrain the mayor's wife, according to Rogers.

Greene, 27, whose stage name was Strawberry, allegedly danced at the rumored Manoogian Mansion party. She was later shot and killed in 2003 and the homicide remains unsolved.

Greene family attorney Norman Yatooma said this new sworn affidavit proves that the Manoogian party was not "urban legend."

"The affidavit is nuclear," Yatooma said.

Rogers said she called a tip line last month to disclose what she knew about the report to Detroit police, but no one called her back.

A police spokesman said Monday evening that the department doesn't operate that tip line and information left on it is anonymous.

James Tate also said Greene's death is an open homicide investigation and police are going through Rogers' affidavit and "all kinds of paperwork about what it said." "There are some things that we found that were questionable," he added.

Michigan Attorney General Mike Cox in 2003 investigated and said he found no evidence that a party had occurred. Michigan State Police investigators also said that they found no evidence of wrongdoing following claims of a cover-up.

A spokesman from Cox's office said Monday that the attorney general and Michigan State Police never were given the police report allegedly seen by Rogers.

"The reports about rumors of this incident are not new," Rusty Hills said. "There were lots of reports. Each was followed up on, but none substantiated. Our conclusion is there was no Manoogian Mansion party and no criminal acts."

Wayne County Prosecutor Kym Worthy also announced in 2005 that her office had planned to conduct an independent review of Greene's death.

Despite denials by the mayor and a state investigation that claims the party was an urban legend, the story has persisted and has been fueled by a $150 million federal lawsuit filed on behalf of Greene's 14-year-old son.

As part of his lawsuit in U.S. District Court, Yatooma has filed subpoenas for text messages or other electronic communications from city employees between 1:30 a.m. and 5:30 a.m. on the day Greene was killed.

He also is seeking global position system coordinates from city-issued pagers that show the location of each employee, Yatooma said.

A federal judge last week ordered the City of Detroit and its communication's carrier, SkyTel, to preserve certain messages from 34 city pagers, including the mayor's pager.

Last week, a former Detroit homicide lieutenant filed a 10-page affidavit in federal court saying he believes a Detroit police officer killed Greene.

The affidavit from former Detroit homicide Lt. Alvin Bowman was filed as part of the federal lawsuit.

The lawsuit alleges Mayor Kwame Kilpatrick and members of the city's police department tried to block the investigation.
