"She'll be served," Zulima Farber told the Associated Press on Wednesday. "She hasn't been because there is no grand jury yet hearing the case."
Farber added that authorities would convene a grand jury in "weeks or months, not years."

Tocchet has been charged with financing the ring that allegedly took non-hockey bets from a number of current players, along with Jones, even though her name is not on public record.
On Wednesday, a lawyer for Jones said she has yet to receive any grand jury subpoena from New Jersey authorities.
Jones allegedly placed large bets through Tocchet. Gretzky has pleaded his innocence and said he never placed any wagers through his wife.
Jones has also denied betting for her husband.
According to the Associated Press, Gretzky asked Tocchet in the wiretapped conversation how his wife could avoid being named as a participant in the investigation.
New Jersey police have said between six and 12 players or people close to National Hockey League teams are believed to have placed bets.
"I think it became a big case only because of the names involved," Farber said. "I think it would have been a routine – if there is such a thing – illegal gambling case if it wasn't for the names of those people involved. However, because there was a trooper involved, it was big to us."
Authorities allege 41-year-old Tocchet and James J. Harney, a state police trooper, were partners in the gambling ring.
Harney has been charged with official misconduct, promoting gambling, money laundering and conspiracy. Another man accused of taking bets, James A. Ulmer, was charged with promoting gambling, money laundering and conspiracy.
Tocchet was granted an indefinite leave of absence on Feb. 8 from his coaching duties by NHL commissioner Gary Bettman.
Additional charges likely will be laid, said Farber, adding that possible charges could be brought against state police officers or other bettors.
Authorities previously said bettors did not break any laws and would not be charged.
Farber defended an assertion by Col. Rick Fuentes, New Jersey state police superintendent, that the gambling ring had connections to the mob, something defence lawyers have denied.
