Original story below:

Indianapolis police were able to track and arrest two people allegedly involved in a Downtown shooting that injured two Clark County judges last week by using their Kilroy's bar receipt, court documents said.

Alfredo Vazquez, 23, and Brandon Kaiser, 41, have been arrested in connection with the May 1 shootings of Clark Circuit judges Drew Adams and Brad Jacobs. Both men are still recovering in Indianapolis.

Vazquez was booked into the Marion County Jail on a preliminary charge of assisting a criminal. Kaiser was held on preliminary charges of attempted murder, aggravated battery, carrying a handgun without a license and battery.

Both men appeared in Marion Superior Court Wednesday morning for a hearing. Prosecutors have 72 hours to file formal charges. Kaiser and Vazquez will be in court again Friday for an initial hearing.

Outside the courtroom Wednesday, Vazquez's mother Kelly Coffman told IndyStar that Kaiser is her brother and her son's uncle.

"My thoughts and prayers are with the judges and their families," Coffman said. "This is a difficult time for all of us.”

According to court documents, the investigation began about 3:20 a.m. May 1 when IMPD officers were called to the the White Castle at 55 W. South St. to investigate a shooting.

When police arrived, Jacobs and Adams were found suffering from gunshot wounds. Investigators also found a spent 9 mm shell casing and a bullet on the pavement.

The judges, who were visiting Indianapolis for a statewide judicial conference, were bar hopping with two others before stopping at the fast food restaurant, police said.

Surveillance footage showed the shooting suspects pulling up to White Castle in a blue SUV, court documents said. In the video, a physical fight breaks out between the two suspects and the two victims, and it ends with one of the suspects pulling out a gun and shooting Jacobs and Adams, police say.

Judges shot:What we know

While police released a portion of the video showing the suspects' vehicle, they declined to release the portion that shows the fight before the judges were shot. In response to an IndyStar records request, IMPD said the video is an investigatory record of a law enforcement agency; therefore, it is withholding portions of the surveillance video.

The video shows the suspects fleeing the scene in the blue SUV.

Two days later, detectives canvassing the area learned that the suspects were in Kilroy's shortly before the shooting. Court documents said that the suspects were kicked out of the bar and grill between 2:30 and 3 a.m., according to security footage.

One of the suspects made a payment at Kilroy's using a credit card, court documents said. The receipt was provided to detectives, and the suspect was identified as Vazquez. They were also able to determine that Vazquez drove a blue Ford Explorer.

Police were able to identify Kaiser by researching known associates of Vazquez, court documents said.

On the afternoon May 4, police began conducting surveillance on Kaiser's home in the 2100 block of Wallace Avenue. After confirming that Kaiser was home, police knocked on his front door and got no response.

Court documents said multiple PA announcements were made for Kaiser to come out, and when he did not comply, a SWAT team was called in. Kaiser eventually exited the house and was arrested.

Vazquez was arrested the same day when police saw him driving his blue SUV in the 600 block of North Wallace Avenue. Search warrants conducted at the homes of the suspects led to the discovered of a black Ruger 9 mm handgun.

When speaking to police, Vazquez admitted to going to Kilroy's and White Castle on the morning of the shooting, court documents said. He told police that he and Kaiser got into a fight with two other men that they did not know. It remains unclear what sparked the altercation.

Vazquez also told police that Kaiser was the one who shot Jacobs and Adams.

Video footage shows Kaiser shooting Adams once in the stomach during the scuffle, court documents said. Jacobs is shot once in the chest while being held by Vazquez.

After Jacobs falls to the ground, the footage shows Vazquez holding him down while Kaiser puts the gun to the center of his chest and shoots him a second time. police said.

Kaiser refused to conduct an interview with the police, court documents said.

Jacobs and Adams remained hospitalized in Indianapolis. There was no evidence they were targeted because they are judges, police said.
