On Wednesday, Waukesha County Court found probable cause to send a Menomonee Falls man to trial for allegedly opening fire inside a bar.Dylan Breidenbach, 22, is accused of opening fire on Sal's Pub and Grill on Nov. 20.Wednesday's preliminary hearing was abnormally long, with a lot of new details revealed, including a possible motive. A detective took the stand at the hearing, revealing that witnesses told him Breidenbach was kicked out of the bar the night of the shooting for harassing customers, particularly female patrons.Those witnesses then said Breidenbach returned 15 minutes later with a gun.Police say he fired a single round into the pub, and a bullet was found embedded into the wall behind the bar. The detective claims Breidenbach told him he was jumped by a group of customers after being kicked out of the bar, and that one of those people held a gun to his head."He indicated that 'Victim A' told him that he was going to kill him," said the detective."Victim A was going to kill the defendant?" asked the prosecutor."Correct," said the detective. "Mr. Breidenbach stated that he told 'Victim A' to quote 'chill' and something to the effect of, 'I've got something for you, too.'"Police say that's when Breidenbach left the bar and went home to grab his AR 10 rifle, which was used in the shooting.On the way back to Sal's, Breidenbach's gun accidentally went off in his truck. Breidenbach's attorney seemed to suggest the one round fired in the bar, was also an accident. The detective pushed back."Isn't it also true he also indicated that the shot in the bar was also an accidental discharge?" asked the prosecutor to the detective."He didn't indicate that to me, no," said the detective. "Not during my interview with him, no."A trial date has not been set for Breidenbach's case. His attorney has filed a request for substitution of Judge for Branch 7, so a trial date will be set when a new judge is assigned.Breidenbach has entered a not-guilty plea.Police said Breidenbach hit a car while driving away from the pub to grab his gun.The criminal complaint reveals four hours after the shooting, he agreed to a breathalyzer test, where he blew .119.The legal level of intoxication is .08.
