The judge at the Drew Peterson murder trial is considering a mistrial request from defense attorneys.
Judge Edward Burmila called a recess Wednesday morning and said he would reconvene proceedings in the afternoon to announce his decision.
Prosecutors asked Thomas Pontarelli, a neighbor, whether he was intimidated by Peterson when confronted by him about helping changing locks.
Pontarelli said he was intimidated and said he told Peterson he "got his message yesterday" when he found a 38-caliber bullet on his driveway.
At that point, the defense objected.
The judge sent jurors out of the courtroom earlier in the day before grilling a prosecutor for allowing a witness to mention a bullet and leave the impression that Peterson left it in the witness' driveway.
"It makes no sense whatsoever the argument what the state put forward to the court," Burmila told the court. He called the move "completely troubling to the court."
Prosecutors argued against a mistrial, denying repetitive errors.
Peterson was charged in the 2004 death of his third wife after his fourth wife went missing in 2007.
Steven Greenberg, a defense attorney, motioned for a mistrial in response to the witness' statement about the bullet he found in his driveway and a hole in a door.
"This is intentionally bringing before the jury evidence the court excluded…evidence everyone knows is improper in a criminal trial," Greenberg said.
Greenberg indicates this is the third or fourth time the state has "deliberately" tried to insert this type of evidence.
