A woman who was with Chicago Blackhawks star Patrick Kane's rape accuser at his lakefront home on the night of the alleged attack has been subpoenaed to appear before a grand jury now probing the allegations.

Former Erie County District Attorney Frank Clark told WRGZ he does not expect any decisions to be made by the panel before the end of the month and hinted that the entire process could take months to play out.

"Right now, it looks as though the decider as to whether or not Patrick Kane is guilty of any criminal conduct or not will be an Erie County grand jury," he added.

The 26-year-old Kane is accused of "overpowering" the woman on the night of Aug. 1, after meeting her and her friend at a downtown bar in his hometown of Toronto and returning to his Hamburg estate to continue partying.

No formal charges have been filed against Kane, though Clark added he suspects the grand jury investigation has been going on for quite some time.

"They may have been listening to the case for a while, and we're just finding out about it," he said. "Or it could be that both the police and the prosecutor felt that they had some investigative work to do before they were comfortable in starting a grand jury action."

Several media outlets have reported at least five teams have contacted the Blackhawks about potential trades for Kane, should the team decide to deal the often-troubled star forward. Back in 2012, following his arrest for a blowup with a taxi cab driver over a fare and rumors of a drinking problem, the Hawks reportedly warned Kane that one more slip up might lead to his banishment from the organization.

The Hawks recently signed Kane to an eight-year, $84 million extension.
