Sgt. Jeffrey Kutz, one of the Sayreville Police Department’s most experienced cops with 22 years on the job, found himself getting booked for a crime on Dec. 18. After allegedly drinking at the home of another officer, Kutz drove his Dodge pickup truck 70 mph into two vehicles on the shoulder of an Old Bridge highway, seriously injuring a man, according to police reports.

Old Bridge officers described Kutz — whom they knew was an off-duty cop in the neighboring town — as drunk, agitated and confused. They said the 57-year-old veteran cop had urinated on himself and was unable to keep his balance, the report said.

A broken-down dump truck was parked in the shoulder of Route 9 South, with a second vehicle parked behind it, when Kutz’s pickup plowed into the car, crushing it against the massive dump truck’s body and trapping the occupant in that second car in the wreckage.

The man had to be extricated and airlifted to Robert Wood Johnson University Hospital in New Brunswick in critical condition. He was reportedly released from the hospital earlier this week.

“I know he feels terrible that someone was hurt," said Kutz’s attorney, Joseph Benedict of New Brunswick. He said the incident was a “life-changing" experience for Kutz, whose aim is to help people. “It’s anathema to his calling in life."

Kutz was charged with third-degree vehicular assault, driving while intoxicated and reckless driving and was suspended without pay from the department.

The Middlesex County Prosecutor’s Office released information about the charges the same day as the accident, but did not say how the crash occurred or release other details. After initially declining to provide the documents in response to a public records request, Old Bridge Police turned over 26 pages of investigative reports last week.

They reveal that a witness estimated Kutz was driving between 90 to 100 mph before the crash, just south of the Route 18 overpass and near Old Texas Road and just after midnight. Benedict said officials told him that the car’s “black box” recorder documented that the truck was traveling 70 mph at the time of the crash.

A disabled dump truck was stopped in the shoulder and a Nissan Altima was parked immediately behind it, police wrote. The man in the car, whose name has not been released, either owned or was otherwise associated with the dump truck that had broken down, according to the police reports. Another man was working on the truck’s engine at the time of the crash but wasn’t injured.

Benedict said his client has no memory of the crash.

After the crash, one officer observed broken pieces of “safety triangles” on the road, indicating the truck driver and his colleague had put up markers so no one would accidentally drive into them.

Old Bridge Officer Scott Henry, the first on scene, reported that Kutz was initially unconscious, but later came to.

“When speaking to Mr. Kutz his eyes appeared to be bloodshot and his speech was slurred. When asking Mr. Kutz where he was coming from, he stated, ‘a driveway.’ Mr. Kutz appeared to be extremely confused and was not aware of where he was at the time,” Henry wrote.

Kutz was told to stay in his truck as EMTs evaluated his injuries, but kept trying to get out, Henry said. The officer said he observed that Kutz was “aggravated” and punching his steering wheel and center console.

When he did get out of the truck, Officer Gregory Goy noted that Kutz lost his balance, needed help walking to the ambulance. . The reports also said officers knew that Kutz was an off-duty cop, but it’s not clear how they learned that.

Kutz was told he would be arrested, taken to a hospital to have blood drawn and later released with a summons, the reports say.

Kutz earns a salary of $134,460 and was hired in 1997. Benedict said his client is “very well-respected” in the department, and his relatives, friends and neighbors have sent in letters of support for him.

“They describe him as the kind of person who’s always there for you," he said.

He is scheduled to appear in Superior Court in New Brunswick on Jan. 24.
