STATEN ISLAND -- Instagram photos allegedly posted by an ex-Linden cop showing shots of whisky at a bar prior to a fatal wrong way crash in 2015 should not be admitted as evidence at trial, his lawyer said Monday.

Pedro Abad's two previous arrests on drunken driving charges should also be excluded, his lawyer Mario Gallucci said after a brief hearing before Judge Stephen Rooney in Staten Island.

"A bad act such as allegedly my client posted on Facebook, the day of that incident or a day prior to that incident - I would try to keep the prosecutor from using evidence such as that before the jury," Gallucci said.

Abad, 29, has pleaded not guilty to a 27-count indictment that includes charges of aggravated vehicular homicide and manslaughter.

Abad was driving home from a Staten Island strip club on March 20, 2015 when he went the wrong way on West Shore Expressway and crashed head-on into a tractor trailer.

Two passengers in his car - fellow Linden officer Frank Viggiano, 28, and Linden resident Joseph Rodriguez - were killed. Another passenger, Linden officer Patrik Kudlac, 25, was critically injured.

Hours before the crash, Abad posted on his instagram account a photo showing shots of whiskey at the Central Park bar in Roselle. Abad and friends went to that bar before going to a strip club Curves in Staten Island.

Gallucci said the judge will hear a motion to suppress that photo from being presented at trial, along with other evidence motions including Abad's past arrests on drunken driving charges.

Abad had two prior drunken driving arrests, one in Roselle where, authorities say, he crashed into the side of a store, and another where he struck a parked car in Rahway. The Roselle case was later dismissed, but he pleaded guilty in the Rahway case and had his license suspended while he was still a Linden police officer.

Gallucci said he is also filing a motion challenging the search warrants used to obtain evidence from the data recorder in Abad's Honda Civic just after the crash, as well as evidence obtained from Abad's blood sample, and evidence from the deployed air bag in his car.

Abad was eventually fired from the police department. Last August, Kudlac was forced to resigned from the force because of his injuries.

Gallucci on Monday said long-delayed testing that he has requested for a sample of Abad's blood - tests to determine if there are any traces of GHB, the so-called date rape drug - are now expected to proceed.

The New York state Office of the Medical Examiner has finally transferred a portion of Abad's blood sample to a lab to test of GHB, Gallucci said.

Gallucci has argued that his client may have been drugged by dancers at the strip club. Gallucci said dancers at other clubs have been charged with putting GHB in customers drinks so they would spend more money.

Relatives of Joseph Rodriguez attended the brief court hearing on Monday, and then spent more than 30 minutes talking with Assistant District Attorney Mark Pallidino. The relatives have attended nearly all of Abad's hearing.

Rooney scheduled the next hearing for Nov. 22. Gallucci said the test for GHB could be completed before that hearing.
