An off-duty Indianapolis Metropolitan Police Department officer has been arrested and charged with attempted murder in the Friday shooting of a detective who was investigating a report of domestic violence involving him and his estranged wife, police say.

The wounded detective, a veteran of the department, Indianapolis police said, was shot at least once in the elbow, and possibly a second time in his side. He is expected to survive his injuries.

The shooting, police said, stemmed from an investigation into the off-duty IMPD officer, later identified by police as 42-year-old Adrian Aurs, who was involved in "some type of domestic incident" with his estranged wife Friday in an apartment on the southeast side of Indianapolis.

About 8 p.m., officers were called to the 6700 block of Valley Ridge Drive, in the Overlook at Valley Ridge apartments, regarding the disturbance; however, because the incident involved an IMPD officer, the department's special investigation unit (SIU) was requested to handle the case.

As the SIU detective began his investigation, police said, Aurs, who is also a veteran of the department, returned and began shooting inside the apartment sometime around 10 p.m.

The detective, who was struck at least once, returned fire, but didn't hit Aurs, police said.

After the shooting, Aurs fled the scene in his personal vehicle. The wounded detective was taken to Methodist hospital, where he remains in good condition.

Over the course of the next few hours, police were able to track the off-duty officer to Cincinnati. Indianapolis police called ahead early Saturday to alert the Cincinnati Police Department that Aurs would be in the area, according to Lt. Steve Saunders of the Cincinnati Police Department.

Cincinnati police vehicles waited along Interstate 75 near mile marker 1.1 and pulled over Aurs before 2 a.m. A SWAT team was called when Aurs chose not to surrender initially, Saunders said.

Traffic was closed on I-75 in both directions and backed up to the Brent Spence Bridge after Aurs' vehicle was stopped in the area of Ezzard Charles Drive, Saunders said.

Saunders said Aurs complied with police instructions during an hour-long standoff and was eventually arrested without further incident.

Aurs will not face charges in Cincinnati, Saunders said, though he "will be facing criminal charges here in Indianapolis once our investigation completes," said IMPD Maj. Rich Riddle.

Saunders said CPD is working to place Aurs in Indianapolis police custody. Aurs is currently in Cincinnati police custody.

At the time of the domestic disturbance, and the shooting that followed, police said, Aurs' two children were inside the apartment. They were not injured.

It was unclear early Saturday morning what exactly happened between the off-duty officer and his wife before police were called, but Riddle said the circumstances were "serious enough of a criminal nature to call in our SIU detectives."

Aurs himself was shot while on duty in 2003, according to IndyStar news reports. He exchanged gunfire with a 23-year-old man who was killed. Aurs was struck, but his bullet-proof vest saved his life, the reports say.

Aurs has a drunken driving conviction on his record. In 2005, he pleaded guilty to a misdemeanor count of operating while intoxicated, and was sentenced to probation, court records show.

In 2012, Aurs was involved in a fatal crash while he was off-duty. Aurs had a small amount of alcohol in his system when his vehicle collided with a car carrying a Greenwood couple, according to IndyStar reports. Prosecutors, though, found that the amount of alcohol was below the legal limit, and the crash was the fault of the other driver. The office declined to bring charges. A 78-year-old Greenwood man was killed in the crash.

Aurs has been immediately suspended without pay, pending termination from IMPD, police said. Detectives have collected Aurs' police badge and ID in light of his suspension and recommended termination.
