MUSKEGON (AP) – A western Michigan woman accused of helping her sister try to hire a hit man to kill the sister’s husband has been bound over for trial.

Vickie Brill, 50, of Ravenna, waived her preliminary examination Tuesday. Brill’s sister, 45-year-old Diane Hart, was scheduled to have her probable cause hearing Wednesday, but prosecution and defense lawyers agreed to a postponement. Another date wasn’t immediately set.

Gene Hart told state police Detective Greg Poulson on Nov. 12 that the sisters had contacted his brother-in-law and that Hart was “subsequently very concerned that he was going to be killed,” Trooper William Coon said in a statement.

The women met in a Norton Shores parking lot with an undercover state trooper, police said. It was there that investigators said an agreement was reached. Prosecutors say $5,000 was to be paid for the killing, with jewelry offered as a down payment.

Muskegon County Prosecutor D.J. Hilson said that state police in the Upper Peninsula worked with the department’s Rockford Post and the West Michigan Enforcement Team to put together the operation that led to the women’s arrest.
