WATCH: Video Shows Cop Involved In Fatal Wrong-Way Crash Arrested In DUI Stop

A police officer from Union County, involved in a fatal wrong-way accident last week in Staten Island, has previously been charged two times with driving while intoxicated, according to published reports.

In one of those cases, a police dashboard camera was recording while he was unable to complete a sobriety test, according to NJ.com.

Officer Pedro Abad, 27, was charged with DWI and careless driving in Roselle in 2011, and he was charged with DWI, DWI in a school zone and refusal to submit to a chemical test after he hit a parked car in Rahway in 2013, the newspaper reported.

In the Rahway case, the police report said “his eyes were bloodshot, watery, I would say were droopy and the subject slurred his speech,’’ according to WNBC.

In the video from that case, obtained by NJ.com, a police officer told him he was going to do some tests and told him to step away from the vehicle.

The Linden police officer initially did not step away, and one of the officers said, “one, two, three,’’ then asked him again.

“Sir, step forward,’’ the officer said.

“If you don’t cooperate....’’ the officer said.

“OK, OK, OK,” Abad interrupted.

“I need you to stand up straight with hands to your side.....Listen, I’m talking to you right now,” the officer said.

Abad made some mention of the “academy” but the police office said that “has nothing to do with this investigation.”

A little more than three minutes after the start of the video, he was handcuffed and placed under arrest.

NJ.com said the outcome of the Roselle case was unclear.

In the Rahway case, Abad’s driver’s license was suspended for seven months, and once it was restored, he had to install an ignition interlock device on his vehicle for 180 days - which ended in September, according to WABC and MyCentralJersey.com. That device measures a driver’s breath alcohol content before the car will start, MyCentralJersey.com reported.

Abad was hired as a police officer in Linden in January 2008, according to MyCentralJersey.

Abad and another Linden officer, Patrik Kudlac, 23, are both in critical condition in Staten Island hospitals, published reports said.

A third officer, Frank Viggiano, 28, and a Linden resident, Joseph Rodriguez, 28, were killed in the March 20 crash.
