A New Jersey cop who was allegedly drunk driving when he caused a wrong-way crash that killed another officer and a friend on a New York City highway uploaded his first post on Instagram and Facebook since the horrific ordeal.

Linden Police officer Pedro Abad, 28, posted a selfie wearing a batman shirt on Wednesday.

In the photo's caption, he wrote a message about his injuries and wrote a tribute to Linden Officer Frank Viggiano and friend Joe Rodriguez, who were killed in the March 20 crash. A third passenger, Patrik Kudlac, 23, was critically injured.

Abad wrote a message about his injuries and wrote a tribute to Linden officer Frank Viggiano and friend Joe Rodriguez, who were killed in the March 20 crash. The post has since been deleted

Abad also thanked followers for birthday wishes in the posts, which have since been deleted. He turned 28 on Tuesday, just a day after appearing in a Staten Island courtroom where he pleaded not guilty to 27 charges.

PEDRO ABAD'S INSTAGRAM POST '1st upload in some time. There are a lot of things going on right now that are just bad for me. I have quite a few injuries and still can't walk normal yet. I have this huge scar on my head, and I"m guessing that's why I don't have a lot of memories. Memories about my life, things that happened during the holiday, or even somewhere happy I may have been with a friend. I don't remember. But I do remember two. Two friends that I had that are not even in this world anymore. One I knew fore 10yrs, the other I knew for 20. Never had a problem with either of these men, and God I do miss them and just wish that I could bring them back and I'll take more pain. There's so much I want to say to say about these 2, but I'll tell them again myself when I see them again one day. Other than that, thank you anyone who supported me on way or another. Thank you for the birthday wishes. God bless you all.. #Batman.' Advertisement

Police said Abad crashed into a tractor-trailer on the West Shore Expressway after the group left a strip club.

Hours earlier, Abad had posted a photo on his Instagram page of three shot glasses filled with what he identified as 'Jack Daniels Fire on the house'.

Tests show Abad's blood alcohol content was 0.24; the legal limit in New York is 0.08

Abad's attorney, Mario Gallucci, said Abad uses crutches and a wheelchair because of leg injuries, one arm is disabled and he has a speech impediment due to 'diminished mental capacity', as a result of the crash.

The photo Abad posted on Wednesday received much praise from his followers.

The posts received hundreds of likes and many commenters sent their well wishes.

'Love and miss you Pedro! I am glad you are ok and will never stop praying for you. You will get through this!' wrote one follower, according to NJ.com.

'Happy birthday! May God continue to bless you and guide you on your road to a full and complete recovery,' another wrote.

Abad's girlfriend, who was with him in court on Monday, wrote: 'Love you honey. You are so strong. Keep doing what you're doing. I'm so proud of you.'

Authorities said that Abad and the three other men who were in his car had been at a Staten Island strip club before the 5am crash in which his Honda Civic smashed into a tractor-trailer while driving the wrong way.

Abad's last Instagram post before the crash was a picture of full shot glasses.

The photo included a caption of a toast he said he had given.

'The three of us, are decent people. There's a decent woman out there for each of us. Sure it's cool to be single every now and then, but I don't give a damn what ANYONE says. At the end of the day, I want a family. I want to settle down. We all do. So here's to finding that which we all hope for.'

After pleaded not guilty to charges on Monday, Abad posted the $25,000 bail, which his attorney had arranged through a bond company.

Six Linden officers were in the courtroom on Monday to support Abad. One of them had driven him to the courthouse. Abad had been suspended from the police department.

Public records show that Abad has been involved in eight accidents since 2005 and had two arrests for drunken driving in the last four years.

During one drunk-driving incident, he plowed through the wall of a convenience store, records show.

He was arrested on a charge of driving under the influence in Roselle, New Jersey, in January 2011 after his car 'put a hole completely through the building' housing a New Way Supermarket, a police report said.

Abad was issued a summons for DUI and reckless driving, but apparently the case didn't conclude in any citations or violations, the state Motor Vehicle Commission said.

Thirteen months later, Abad was charged with DUI in Rahway, New Jersey. A police dashboard camera video showed him weaving, wobbling and slurring his words as he attempted to complete a field sobriety test.

Abad's driver's license was suspended after the second arrest, beginning in October 2013 and concluding in May 2014, the Motor Vehicle Commission said.

A judge then required Abad to fit his car with an ignition interlock, which won't allow a vehicle to start until the driver blows into a device to measure his blood-alcohol level and is deemed sober. The interlock device was removed last September, the commission said.

Abad is scheduled to have surgery on his legs on September 29.

His next court appearance is a month later, on October 29.
