Authorities completed their extensive search of a canal Tuesday for any signs of missing mother of two Stacy Peterson.

Illinois State Police Sgt. Luis Guitierrez told FOXNews.com that the canal search is over, but authorities still plan to search other areas of interest.

“We’ve covered the areas that we were searching,” Guitierrez said.

Divers searched a Chicago canal after reports that a cell phone ping led authorities to the area. Cell-phone records showed that Drew Peterson, Stacy's husband and a suspect in her disappearance, was near the canal on the day she disappeared.

Joel Brodsky, Drew Peterson's attorney, disputed reports that his client was near the canal. Brodsky said cell phone records are unreliable.

Peterson hired two private investigators to search for his missing wife, Brodsky said. They are reviewing electronic leads, including cell phone records and text messages.

Authorities sifted through the frozen waters of the Illinois Michigan canal filled with debris in their ongoing investigation in the search for Peterson, who was reported missing on Oct. 29 after she failed to show up at a friend's house.

Cell-phone records indicate that Drew Peterson, a suspect in his wife's disappearance, received a call from Cassandra Cales, Stacy's sister, according to a report in the Chicago Sun-Times.

Peterson, a former police sergeant, denies any involvement in his 23-year-old wife's disappearance and claims that she left him for another man.

Meanwhile, on Tuesday, police dismissed a man's accusations against Drew Peterson, who claimed that he was a victim of police brutality during an arrest earlier this year.

Timothy Brownlee claimed that Peterson injured his hand and used racial slurs during an arrest. Brownlee said he is suing Peterson, two other police officers and the Bolingbrook, Ill. police department.

According to police, Brownlee was arrested in May 2007 after a neighbor complained that he was using vulgar language. Brownlee would not cooperate with the booking process after his arrest.
