The road rage incident Tuesday morning began like so many others: Two drivers — one angry at the other's driving — flipped each other off.

But then they drew guns. Then they fired from their driver seats.

When the firing stopped, though, it was a passenger who was fatally shot. Brandy Brock was 31.

The details of the east-side shooting are contained in a probable cause affidavit filed Thursday in Marion Superior Court. Andrew Holder, 47, was charged with criminal recklessness, a low-level felony, and carrying a handgun without a license, a misdemeanor.

Holder, however, was not the one who shot Brock, police say. Brock, sitting in the passenger seat of Holder's car, was struck in the back by a bullet fired by the other driver.

It's unclear if that driver, only identified as J.G. in court documents, will face any charges. It's also unclear whether anyone will face murder or felony murder charges in Brock's killing.

Questions posed to Marion County Prosecutor Terry Curry's spokeswoman, Peg McLeish, on Thursday afternoon were not immediately returned.

Two spokesmen for the Indianapolis Metropolitan Police Department, officers Michael Hewitt and Aaron Hamer, declined to answer several other IndyStar questions about the shooting.

The shooting happened around 11:30 a.m. Tuesday, according to a police report.

Holder and the other driver were moving west along 38th Street when a disagreement began, according to court documents. Holder told police that the other vehicle was driving aggressively and purposely braking in front of him.

The other driver, though, told police that he swerved around a sewer cap.

A passenger in that car told police that both drivers were racing and flipping off each other.

When they pulled up to the intersection of East 38th Street and North Arlington Avenue, the other driver said he stopped his vehicle behind Holder's car. Holder then stuck a handgun out of his driver-side window and fired one shot toward the other driver, according to the probable cause affidavit.

When the other driver saw the gun, he said he grabbed his gun from between the gear shift and his seat. He opened his door, he said, and fired one round back as Holder's car drove away.

The bullet entered the car to the right of the trunk's keyhole, continued through the back and front seats and into Brock's back, court documents say.

The other driver said he knew about the two passengers but tried to shoot at the driver, according to court documents.

Holder, meanwhile, told police that he did not have a gun and no one in his vehicle fired a weapon at the other driver. Holder said he previously owned a revolver but said it was stolen five weeks ago. Police did not find a weapon on Holder or in his car.

But a back-seat passenger in Holder's car disputed his account, according to court documents. The passenger said he told Holder not to do it, but Holder pointed the gun and fired a shot toward the car behind them.

The passenger then heard another shot and saw that Brock had been hit.

A bystander, interviewed by an IMPD detective, also said that the first shot came from Holder's car. Then the other driver shot back.

After Brock was hit, Holder drove to a fire station seeking help for Brock. Brock was taken to Eskenazi Hospital and pronounced dead at 12:31 p.m., according to the court documents.

The other driver, meanwhile, called 911. He gave his handgun to officers.

Holder remains held in Marion County Jail. A court hearing has been scheduled for 8:30 a.m. Friday.

Criminal recklessness is a Level 6 felony that typically carries a potential sentence of six months to 2.5 years in state prison.
